Question

When magnetic field is acting towards north and current is moving in east to west direction through a conductor, then the conductor will move direction

A.

in the upward

B.

towards left

C.

towards right

D.

in the downward

Correct option is D

The correct answer is (D) in the downward.

Explanation:
Using Fleming's Left-Hand Rule:

  • First finger: Direction of magnetic field (towards north).
  • Second finger: Direction of current (from east to west).
  • Thumb: Direction of the force or motion of the conductor.

With the magnetic field towards the north and current flowing from east to west, the conductor will experience a force in the downward direction.

Incorrect Options Explanations:

  • (A) In the upward: Incorrect, the force is directed downward.
  • (B) Towards left: Incorrect, the force is directed downward, not left.
  • (C) Towards right: Incorrect, the force is directed downward, not right.

Information Booster:

  • Fleming's Left-Hand Rule: Describes the direction of force acting on a current-carrying conductor in a magnetic field.
  • Electromagnetic Force: Key principle in the working of electric motors and generators.
