producing an electric current 6 marker

Question 1

how do you produce an electric current by the relative

movement of a magnet and a coil of wire in the large-scale generation of electrical energy

Answer 1

electricity induced in the coil is transferred to a circuit through the slip rings, which touch carbon brushes attached to the circuit. the slip rings and brushes allow electricity to flow between the moving coil and the stationary circuit without wires becoming twisted. each side of the coil goes up through the magnetic field and then down again, the direction of the induced current changes. this is alternating current

Question 2

how do you produce an electric current by the relative

movement of a magnet and a coil of wire in small scale

Answer 2

by moving a magnet in or near a coil of wire. as you move the magnet, the magnetic field through the coil changes, this change in the magnetic field induces a voltage, and a current flows in the wire. the direction of the voltage and current depends on which way you move the magnet.
