Question

fill in the word that completes the statement. the direction of the magnetic field produced by an electric current will change when the direction of the changes.

Explanation:

To determine the word that completes the statement, we rely on the principles of electromagnetism. The magnetic field produced by an electric current is related to the direction of the current. By the right - hand rule (or other relevant electromagnetic principles), when the direction of the electric current changes, the direction of the magnetic field it produces also changes. So the word that should fill in the blank is "electric current".

Answer:

electric current
