What is an electromagnet? * 10 points A metal magnet that has electricity running through it. A metal magnet that creates an electric field. A magnetic field caused by electric current. A magnetic field caused by moving a magnet.

A magnetic field caused by electric current.

Explanation:

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.

A magnetic field caused by electric current

Explanation:

An electromagnetic is a magnetic field cause by electric current. It is a magnet which has the joint interaction of electric and magnetic forces.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
