Question

Current-carrying wires produce which kind of fields?

a
frictional
b
gravitational
c
chemical
d
magnetic
Bot
The answer is (d) magnetic fields. Current-carrying wires produce a magnetic field that is perpendicular to the direction of the current flow. This is known as Ampere's law. The strength of the magnetic field produced by the current depends on the magnitude of the current and the distance from the wire.
