Question

Which of the following is not a property of a typical magnet?

• A. None of these
• B. Exert an attractive or repulsive force on other magnets
• C. Have an effect on electrical conductors when the magnet and conductor are moving in relation to each other
• D. Attract certain materials - such as iron, nickel, cobalt, certain steels and other alloys

Answer 1

Answer: (A), (B), (C)

The correct options are
A

None of these

B

Exert an attractive or repulsive force on other magnets

C

Have an effect on electrical conductors when the magnet and conductor are moving in relation to each other

A magnet attracts magnetic materials - such as iron, nickel, cobalt, etc. Any magnet has two poles, i.e., north and south pole. We know that like poles repel and unlike poles attract. Thus, a magnet attracts or repels another magnet. When a current-carrying conductor moves in a magnetic field, it experiences a force. Hence, a magnet has an effect on a current carrying conductor. However, a magnet does not attract wood or plastic
