Question

Magnetic force on a closed current-carrying circuit placed in a uniform magnetic field is ______.

विकल्प

• zero as field is uniform.

• non zero as field is non zero.

• zero as vector sum of length element of circuit is zero

• non zero for finite value of current.

Answer 1

Magnetic force on a closed current-carrying circuit placed in a uniform magnetic field is zero as vector sum of length element of circuit is zero.
