Unit 5 Test Review Electricity and Magnetism

From this illustration, we can conclude that

• magnetic force is strongest in the middle of the magnet.

• magnetic force is strongest at the poles of the magnet.

• the poles of the magnet have different strengths.

• magnetic force is weakest at the poles of the magnet.

Magnet A is suspended above magnet B because

• the magnets are attracting each other as their opposite poles are facing each other.

• The magnets are repelling each other as their opposite poles are facing each other.

• The magnets are repelling each other as their like poles are facing each other.

• The magnets are attracting each other as their like poles are facing each other.

  The magnets are attracting each other as their like poles are facing each other.
