Question

turning a magnet very quickly would be best used to create a radiation. b light waves. c an electric current. d a convection current.

Explanation:

Turning a magnet quickly induces electromagnetic induction, which generates an electric current (Faraday's law). Radiation, light waves, and convection currents aren't directly created by quick magnet rotation. So the best answer is C.

Answer:

C. an electric current.
