MCQ
Electricity flows through a very long solenoid. Some statements are given below related to the magnitude of the magnetic field developed inside the coil. Find out the correct ones and write them down:
  • A
    It is zero
  • B
    It will be the same at all points
  • C
    It gradually decreases towards the ends.
  • D
    It gradually increases towards the ends.
✓

Answer

  1. It will be the same at all points
    Explanation:
    The field lines inside the solenoid are in the form of parallel straight lines. This indicates that the magnetic field is the same at all points inside the solenoid. That is, the field is uniform inside the solenoid.
