Can a moving bar magnet exert a force on a stationary charge? Explain.

Text Solution

Verified by Experts

Yes, in case of a moving bar magnet, magnetic field is changing and changing magnetic field produces an electric field. As we know that
`vec F= q( vec E+ ( vec v xx vec B))`
For a stationary charge, `vec v = 0`, therefore,
`vec F = q vec E`
Thus the force acting on the charge is due to electric field.
