Question

Which of the following best compares how magnetic fields are used in electromagnets and generators? Question 3 options: In an electromagnet, a magnetic field is used to produce and electric current. In a generator an electric current is used to produce a magnetic field. In an electromagnet an electric current is used to produce a magnetic field, in a generator a magnetic field is used to produce an electric current. In an electromagnet and a generator, an electric current is used to produce a strong magnetic field.

Answer 1

Answer:

In an electromagnet an electric current is used to produce a magnetic field; in a generator a magnetic field is used to produce an electric current.  

Explanation:

An electric current moving through a wire produces a magnetic field (electromagnet), and

Wires moving through a magnetic field generate an electric current (generator).
