Question

What is the result of increasing the speed at which a magnet moves in and

out of a wire coil?
A. The current in the wire increases.
B. The magnetic field around the magnet decreases.
C. The current in the wire decreases.
D. The magnetic field around the magnet increases.

Answer 1

A. The current in the wire increases.

Step-by-step explanation:

Increasing the speed at which a magnet moves in and out of a wire coil increases the current in the wire.

This phenomenon shows the inter-relationship between electricity and magnetic fields.

• Magnetic fields are induced by passage of electric current.
• Also, electric current can be produce by magnetic fields.
• When the speed at which a magnet moves in and out of a wire coil increases, the current also increases.
