But what are these poles? What do they do? And how can you tell which is which? When you have more than one magnet, like or same poles repel, or push, each other.
Opposite poles attract, or pull, each other. In other words, the north pole of one magnet will click together with the south pole of another magnet, and two north poles will push each other away.
One easy way to tell which pole is north and which is south is to set your magnet near a compass. Wanna know a secret? This works because the needle in a compass is actually a magnet! Another way to tell which is north and which is south is by dangling your magnet from a string.
Magnets Learning Objectives By the end of this section, you will be able to: Describe the difference between the north and south poles of a magnet. Describe how magnetic poles interact with each other.
Universal Characteristics of Magnets and Magnetic Poles It is a universal characteristic of all magnets that like poles repel and unlike poles attract. Note the similarity with electrostatics: unlike charges attract and like charges repel.
That is why the north pole of your compass is attracted toward the geographic north pole of the Earth—because the magnetic pole that is near the geographic North Pole is actually a south magnetic pole! Figure 3. Unlike poles attract, whereas like poles repel. See if you can show this for two refrigerator magnets. Will the magnets stick if you turn them over?
Why do they stick to the door anyway? What can you say about the magnetic properties of the door next to the magnet? Do refrigerator magnets stick to metal or plastic spoons?
One is vertical and one is horizontal. That is not true. Take Seattle for example. The Magnetic North Pole as of today is above Siberia This is obviously to the West of Seattle. But a compass in Seattle will point JT Allyn, I am more concerned with the fact that the deteriorating magnetic field allows more and more solar and cosmic radiation to bombard the Earth.
Have you seen the stats on rapid rise of cancer patients? I have read how the each switched poles north for south, south for north long ago and that they expect it will happen again. My question is, when do we expect that to happen next? I am stunned by the pitiful ignorance displayed in many of these posts. Please folks go back to the 5th grade and try to learn something!
I suggest you read or watch interviews of admiral bryd. Plastic noun , the substance, is only so called because it is, either permanently or at some point during its manufacture, plastic adjective. Plastic as an adjective has been around for much longer, meaning malleable, which is why plastic is so called for short, having many different types with long unmemorable names.
Long term, that is probably more harmful than climate change, which I doubt is caused by humans though certainly exacerbated by them. Us humans will never have control of the North magnetic. The massive vortex force above us will see to that and we will have to accept that as years go on there will be a surprise where as the poles do flip. Once the gift of sound and vision is reached not many will understand. This circular motion from mantle convection is the main mechanism that tears plates apart at divergent boundaries.
But yes I should have the lithosphere above it in that figure. I appreciate that for pointing it out. To suppose the cause of polar shift, iron relocated by mining in Minnesota, and copper from Montana? Could have affect, so we should put it all back??? Andromeda galaxy is closing on The Milkyway, our solar system crossed the equatorial center of the Milkyway science says.
These are 2 possibilities for the changes around us, comfort by saying we did this and have power to change it is ludicrous. Magnetic inclination is magnetic dip from the horizontal. I am neither scientist nor writer, but thank you for an informative read, I may and most likely have this wrong, but here goes… true north is the point at which all longtiude lines meet? The true North Pole just keeps the world map the righ way up, in that instance for our human brains comprehension? My last thought, removing oil and gases we use as energy surely the fine mechanics of the guts of earth, perhaps need those resources to maintain the balance?
For example, my car with oil or pertrol, the components in the engine cease to work! Could the removal of gases and oil, impact on earths rotation? The pole moves? Why then does my compass point exactly where it has always pointed. The earth nor its poles are moving anywhere. This is just more made up non-sense. Need proof? Show me a video of a person standing on either pole looking at their compass and video this compass pointing south in all directions as the person holding the compass turns degrees.
Three people should be involved, the person holding the compass, the person recording the other person holding the compass as it clearly shows the direction and a third person recording the other two clearly not interfering with the compass. You will never see this because it is not possible. The one thing that could easily prove that there is a south pole cannot be done.
There are strange things happening solar system wide. The ice caps on Mars are melting, The Great Eye Of Jupiter is disappearing, our sun glows white now not yellow as in my past. Something is affecting all of it. Climate change is made up. Carbon dioxide is what we exhale. The only answer to that is plant trees, electric cars, kill half the population. No they want to charge us for the air we breathe.
If after you believe anything the Governments says? We are in trouble! Lol the part about a magnetic field flip taking somewhere between , to , years is just comical.
Outside of its slow creep we see today, mind you that the North Pole has been moving much faster than this over the past few decades, what other evidence do you have to support this?
There is so much evidence to the contrary and can be seen on every continent in the world. It can be seen in the geography of our planets, countless pre history ancient archeological sites show signs of it, our science today shows evidence of it, they have found Mammoths with intact flowers in their mouths from an event that froze them instantly. And all of them point to the potentiality of it happening in the span of a single day! Look into it! This is the directive property of magnets.
Effects[noun] affect[verb] us. Feel free to ignore the rest of my blathering, if that bothers you as much as it bothers me. What a fascinating wander and shift this conversation has had over the years. Some interesting science, some interesting theories, some interesting anti-science, and some interesting cra-cray nonsense. Plenty of metal on the surface, however, so locally, glacial shift and melting could occasionally, possibly, tweak a compass by a small amount over time, especially if you were exploring the glacier area itself.
Conspiratists conspirisists? Far from a perfect sphere, but more perfect in texture and shape than your average ping pong ball or steel bearing.
They generally stop in the bulk of Canada, where the differences in magnetic North are still pretty small. Penguins might tell another story about the wandering magnetic South pole, but just trill and squawk nonsensically when interviewed.
In regards to the molten core shifting the way Earth moves, it undoubtedly does. The inertia of our entire world, however, remains steady enough that those shifts are slow and steady, that we can scarcely measure it. This post was not intended to make light of previously expressed ideas, nor ideas to come afterward. Good day. The outer core being liquid and certainly volatile, would this movement not change the angle of the earth on its axis.
Hi all please could anyone clarify if Obliquity is factored in when establishing True North and coordinates? I am a guitarist and my choice of instrument is a Fender Stratocaster, which has single-coil pickups.
In those pickups are six magnets, all in a row which is part of what makes the guitar have its unique sound. As most guitarists know, guitars with single coil pickups are noisy, introducing AC hum especially when the amplifier is cranked up and high gain and volume is used.
So it is not the positional relationship of the guitar to the amplifier which affects the noise, but that of the magnetic poles. Try it; it works! Sam Moe, you must be trolling. Obviously the sun would still rise in the same place if the magnetic poles reversed.
I truly believe that this is a sign of being closer, each day, to the Day of Judgement. When that flip happens magnetic pole flipping , the sunrise would be from the west instead for the east. Have you thought about that?? Have you ever watched one tie his shoes? I often think about the birds who fly to the North and South pole regions. Unlike us humans, birds can actually see the true magnetic gravitational force. Therefore, it would make sense for them not to fly over the North pole area openings as the opening has a a force that would pull them in.
Once you know where that is, you can reason where the true north really is. Because the magnetic north pole does move, you would think this to be true for birds avoiding flying in that area let alone planes. What concerns me about the changes in placements of the magnetic poles in the north is that it is shifting closer to home. It sort of reminds me of the black hole theory in space where matter gets sucked in with it if too close to it.
Could this theory also be the case with the changing magnetic true North pole location? Nobody has mentioned the changes in all our planetary bodies in last 10yrs our sun this year has tilted by 6 degrees due to an unknown influence if you believe NASA these days.
BTW this has nothing to do with global warming. Even our moon has strange changes going on. I have noticed this winter especially, the Deer population has increased dramatically.
I have seen multiple herds of Deer grazing around and also I have seen the Deer in the middle of town grazing on grass and twigs. They are not disturbed by the local residents nor the local pet dogs. The porcupine population is increasing as well along with more herds of Elk.
As far as insects….
