Use the term magnetic domain in your discussion. 2Which of the following are true regarding Earth’s magnetic field? Check all that apply. the magnetic poles drift about 10-15 km per year scientists are not really sure why Earth acts like a magnet the magnetic north pole is actually the south pole of Earth’s “magnet” the magnetic north pole is stationary 3You heat up a piece of metal and bring it close to a strong magnet. You let the piece of metal cool while in place. What happens? The induced magnet will stay a magnet after it cools. Nothing happens in this case, because there was no contact between the metal and strong magnet. The magnetic ability of the original strong magnet will be reduced by the presence of the non-magnetic material. After the induced magnet is moved away from the strong magnet, it will return to its non-magnetic form.arrow_forwardWhat is the best way to separate a mixture of pencil shavings and paper clips? O A.
