Do circular electric lines of force exist ? why? what about magnetic lines of force?

Answered by drwls
Yes to both questions. Current in a straight wire produces circular concentric magnetic lines of force around the wire. A changing magnetic field produced circular lines of electric force around the magnetic lines of force.
