MCQ
Mark the incorrect statement.
  • A
    electric current produces magnetism.
  • B
    magnets can produce electric current.
  • ✓
    magnets can't produce electric current.
  • D
    $a$ and $b$
✓

Answer

Correct option: C.
magnets can't produce electric current.

A magnet can generate electric current by the means of electromagnetic induction. When there is a relative motion between a coil and a magnet, the magnetic flux linked to the coil changes due to that relative motion. This change in magnetic flux will induce a current in the coil, which is known as induced current.
