A wire in a lamp that is turned on would have a magnetic field around it. TRUE or FALSE.

Weegy: A wire in a lamp that is turned on would have a magnetic field around it. TRUE. User: Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor. (More)
