MCQ
Electric current produced by a moving straight wire in a magnetic field is?
  • A
    Magnetic Current
  • B
    Electrostatic Current
  • ✓
    Induced Current
  • D
    None
✓

Answer

Correct option: C.
Induced Current
Electric current produced by a moving straight wire in a magnetic field is Induced Current The current due to the emf induced due the change in magnetic flux of a coil when a magnet is inserted in it is induced current.When in a coil there is change in magnetic flux an emf is generated such that it opposes the change in magnetic flux. The current generated due to this emf is known as induced current.
