Question

a student coils a copper wire around a bar magnet. which action will cause the device to generate electricity? the student uses a horseshoe magnet instead of a bar magnet. the student insulates the copper wire with plastic. the student connects the copper wire to a light bulb. the student moves the bar magnet through the copper wire coils.

Explanation:

To generate electricity, electromagnetic induction (changing magnetic flux through a coil) is needed. Moving the bar magnet through the copper wire coils changes the magnetic field through the coil, inducing a current. Other options don't create the necessary flux change.

Answer:

The student moves the bar magnet through the copper wire coils.
