What is a dynamo?
A) a rotating body containing fluid whose movement maintains the rotation
B) a rotating magnet whose magnetism maintains the rotation
C) a rotating device that changes motion energy to electrical energy
D) a rotating body that contains fluid and magnetism

Question

Quizplus · Accepted Answer

A dynamo is a device that converts motion energy into electrical energy through electromagnetic induction. It typically consists of a rotating coil of wire and a stationary magnet. As the coil rotates in the magnetic field, the magnetic field induces a voltage in the wire, producing electricity. Option A describes a fluid dynamo, option B describes a permanent magnet motor, and option D is not an accurate description of a dynamo.
