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 ______

• A. $20 V$
• B. $16 V$
• C. $8 V$
• D. $12 V$

Answer 1

Answer: (B)

$16 V$

Answer 2

The correct answer is (B) : $16 V$

Induced emf across the ends =Bvℓ
=2×8×1=16V
