Question

Magnetic field is decreasing with time. The direction of induced current will be

• A. Clockwise
• B. Counter clockwise
• C. No current is induced
• D. Data insufficient

Answer 1

Answer: (B)

Counter clockwise

$Solution:$ The induced current will be counter clockwise . As the bar moves upward through the constant magnetic field region, the area of the loop decreases, so the flux through the loop decreases. By Lenz's law, any induced current will tend to oppose the decrease.

$So,the$ $correct$ $option:B$
