3) Which type of current in a circuit will produce a magnetic field?
a) direct current only

b) alternating current only

c) both direct and alternating current

d) Neither direct and alternating current

c) both direct and alternating current

Because Ampere's Law, a magnetic field is produced whenever an electrical charge is in motion. So, both kind of currents produces a magnetic field when electrical current is flowing through a wire.

d they tend to lose electrons and become cations.

explanation:

i would say the answer is food.

hope this !
