question 13 of 20
what happens when an electric current passes through a coil of wire instead of a single straight piece of wire?
a. the electric field created is stronger.
b. the magnetic field created is weaker.
c. the electric field created is weaker.
d. the magnetic field created is stronger.

Explanation:

When an electric current passes through a wire, a magnetic - field is produced. In a coil of wire, the magnetic fields of each turn of the wire add up, creating a stronger magnetic field compared to a single straight piece of wire. The electric field is not directly affected by whether it is a coil or a straight wire in this context.

Answer:

D. The magnetic field created is stronger.
