Question

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 distance between the coil and the magnet a number of times.
what happens to the amount of voltage generated when the distance between the magnet and coil increases?

• the generated voltage increases as the distance increases.
• the generated voltage decreases as the distance increases.
• the generated voltage remains the same as the distance increases.

Explanation:

Electromagnetic induction generates voltage based on magnetic flux through a coil. As the distance between the magnet and coil increases, the magnetic field strength passing through the coil weakens, reducing the induced voltage.

Answer:

The generated voltage decreases as the distance increases.
