Question

Flashing lights on a small toy are controlled by a circuit. When the toy is turned on, an electric current flows through the wires in the circuit. What is something that happens when an electric current flows through the circuit?
A.
a magnetic field is induced
B.
a gravitational field is induced
C.
gravity is converted to magnetism
D.
electricity is converted to gravity

Answer 1

A. a magnetic field is induced.

Moving electric charges (an electric current) produce a magnetic field around the wire (Ampère's law/Biot–Savart). Gravity is not created or converted by ordinary electric currents.
