Question

A very long uniformly charged rod falls with a constant velocity V through the centre of a circular loop. Then the magnitude of induced emf in loop is-

• A. $\frac{\mu_{0}}{2\pi}$lV²
• B. $\frac{\mu_{0}}{2}$lV²
• C. $\frac{\mu_{0}}{2\lambda}$V
• D. Zero

Answer 1

Answer: (D)

Zero

Answer 2

As charged rod is moving with constant velocity \ Magnetic field due to its motion is also constant, no change in flux so no emf.
