Which statements correctly describe the relationship between a solenoid and an electromagnet? check all that apply. a. a solenoid is an electromagnet. b. a solenoid carries an electric current. c. an electromagnet is a solenoid with a metal core. d. an electromagnet induces an electric current in a solenoid. e. a solenoid induces a magnetic field in a metal core.

B. A solenoid carries an electric current.

C. An electromagnet is a solenoid with a metal core.

E. A solenoid induces a magnetic field in a metal core.

Explanation:

An electroiman is a large number of wire turns (solenoid) that are wrapped around a magnetic core made of a ferromagnetic or ferrimagnetic material, such as iron. The metal core is composed of "tiny imans", when a current is passed through the solenoid, its magnetic field penetrates the iron, and causes the "tiny imans" to aligning parallel to the magnetic field, creating a large magnetic field.
