Question

A wire of length 1 m moving with velocity 8 m/s at right angles to a magnetic field of 2 T. The magnitude of induced emf, between the ends of wire will be ______.

विकल्प

• 20 V

• 8 V

• 12 V

• 16 V

Answer 1

A wire of length 1 m moving with velocity 8 m/s at right angles to a magnetic field of 2 T. The magnitude of induced emf, between the ends of wire will be 16 V.

Explanation:

Given: Magnetic Field (B) = 2 T

Length (l) = 1 m

Velocity (v) = 8 m/s

Induced EMF (e) = Blv

= 2 × 1 × 8

= 16 V
