Question

4 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. electricity is converted to gravity b. a magnetic field is induced c. gravity is converted to magnetism d. a gravitational field is induced

Explanation:

According to the principle of electromagnetism, when an electric - current flows through a conductor (such as the wires in the circuit), a magnetic field is induced around the conductor. Electricity cannot be converted to gravity as they are different fundamental forces. Gravity also cannot be directly converted to magnetism, and an electric - current does not induce a gravitational field.

Answer:

B. a magnetic field is induced
