Question

Based on the diagram, why does the lightbulb light when the loop rotates, and what is the energy change involved?

Responses

When the wire moves in an electric field, electrons in the wire move and become mechanical energy. The mechanical energy causes the light to glow. Electrical energy used to rotate the loop is converted to light energy.

Answer 1

Answer: When the wire moves in a magnetic field, electrons in the wire move and become an electric current. The current causes the light to glow. Mechanical energy used to rotate the loop is converted to electrical energy.

Step-by-step explanation:

In the given scenario, the rotating loop of wire creates a changing magnetic field. According to Faraday's law of electromagnetic induction, this changing magnetic field induces an electric current in the wire. The electrons in the wire move as a result of this induced current, and this current flows through the lightbulb, causing it to light up.

Therefore, the energy change involved is the conversion of mechanical energy (from rotating the loop) into electrical energy (as the induced current flows through the lightbulb), which then produces light energy in the lightbulb.
