1. The magnetism of the middle part of the bar magnet ( ), the magnetism of both sides ( ).

2. The part with the strongest magnetic force on the magnet is called ( ).

3. The magnet has ( ) poles.

judge

1. Magnets can attract iron, so the material that can be attracted by magnets must be iron. (X)

2. The magnetic force of each part of the bar magnet is the same. (X)

3. The middle of the bar magnet is non-magnetic. (X)

4. A magnet has two magnetic poles, the south pole and the north pole. (√)

Thoughts after class:

If a bar magnet accidentally breaks into two pieces, how many poles does it have?
