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 strength of the magnet a number of times.
what happens to the amount of voltage generated when the magnet becomes stronger?
☑ the voltage produced decreases when the strength of the magnetic field increases.
☑ the voltage produced increases when the strength of the magnetic field increases.
☑ the voltage produced stays the same when the strength of the magnetic field increases.

Explanation:

Brief Explanations

The provided text states that the amount of generated voltage depends on the strength of the magnet. Electromagnetic induction principles show that a stronger magnet creates a stronger magnetic field, which induces a larger voltage in a nearby coil when the magnet moves relative to it.

Answer:

The voltage produced increases when the strength of the magnetic field increases.
