Question

not move back and forth.
when the magnet turns in the coil of wire, the coil generates a sine wave voltage. when the magnet has rotated once, the voltage has been positive once and negative once. this is one cycle.
the amount of voltage generated depends on:

• the rotation speed of the magnet.
• the strength of the magnet.
• number of turns in the coil.
• the distance between the coil and the magnet.

change the number of turns in the coil several times.
what happens to the amount of voltage generated when a coil has fewer turns?

• the amount of voltage generated stays the same.
• the amount of voltage generated decreases.
• the amount of voltage generated increases.

Explanation:

The text states that the voltage generated by the coil depends on the number of turns in the coil. Electromagnetic induction principles show that fewer coil turns mean less magnetic flux linkage, reducing induced voltage.

Answer:

The amount of voltage generated decreases.
