Jill uses a magnet to pick up a nail. Then, she touches the nail to a paper clip and picks up the paper clip. What will most lik
ely happen when she pulls the magnet away from the nail? The paper clip will stay attached to the nail because the nail is now a permanent magnet.
The paper clip will stay attached to the nail because the paper clip is now a permanent magnet.
The paper clip will fall off of the nail because the nail was only a temporary magnet.
The paper clip will fall off of the nail because the nail is now magnetized in the opposite direction.
e. The paper clip will likely fall off because it wasn't attached to the nail long enough to be magnetized.
The same answer would apply to the nail. It likely was not held onto the magnet long enough to pick up a magnetic force that would be strong enough to overcome the gravitational force pulling on the clip.
Of the four answers you have given us, I would agree with C. But as I've argued above, the real reason is likely there.
