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.
