Question

When current is parallel to a magnetic field, then force experience by the current-carrying conductor placed in a uniform magnetic field is ____________.

Options

• Twice to that when the angle is 60°

• Thrice to that when the angle is 60°

• zero

• infinite

Answer 1

When current is parallel to a magnetic field, then the force experienced by the current-carrying conductor placed in a uniform magnetic field is zero.

Explanation:

If the current direction is parallel to the magnetic field, the magnetic field will exert no force on the conductor.
