How does a rotating coil inside a magnetic field generate electricity?

The rotating coil allows a different amount of magnetic field lines through the loop while it spins. This means the magnetic field is changing, which induces an electric current.

The rotating coil changes the electric field as it spins. A changing electric field generates a magnetic field, which induces an electric current.

The rotating coil allows the same amount of magnetic field lines through the loop while it spins. This means the magnetic field is constant, which induces an electric current.

The rotating coil maintains a constant electric field as it spins. A constant electric field generates a changing magnetic field, which induces an electric current.

Shawn · Answer 1

Answer:option A is correct.

Explanation:Because in option C : magnetic field is constant.

Option D:Because in option D, electric field is constant.

Because constant electric and magnetic fields cannot produce electric current.

Option B:A changing electric field cannot produce magnetic field.

Option A:Because a changing magnetic field can produce electric current.
