Question

a conductor is moving perpendicular to a variable magnetic field and the direction of magnetic field is reversing periodically then the polarity of induced emf across the conductor is​

Answer 1

Answer:

Explanation: We know by Fleming Right hand Thumb Rule direction of induced current will always depends on direction of magnetic field so if it changes periodically then polarity chnages as well in the conductor.

Thank you
