Question

Evidence exists that a changing magnetic field produces an electric current. Develop two hypotheses to test the question.

Answer 1

Two hypotheses that can be tested to determine if a changing magnetic field produces an electric current are: 1) If a changing magnetic field is applied to a wire, then an electric current will be produced. 2) If an electric current is passed through a wire, then a changing magnetic field will be produced.

Step-by-step explanation:

Two hypotheses that can be tested to determine if a changing magnetic field produces an electric current are:

1. Hypothesis 1: If a changing magnetic field is applied to a wire, then an electric current will be produced.
2. Hypothesis 2: If an electric current is passed through a wire, then a changing magnetic field will be produced.

These hypotheses can be tested through experiments using a wire, a magnet, and a galvanometer. The first hypothesis can be tested by moving a magnet near a wire and observing if a current is induced. The second hypothesis can be tested by passing an electric current through a wire and using a compass to observe if the magnetic field changes.
