Question: A loop of wire is placed in a changing magnetic field. What phenomenon is observed?

Options:

Correct Answer: Electromagnetic induction

Solution:

A changing magnetic field induces an electromotive force (EMF) in the loop, a phenomenon known as electromagnetic induction.

A loop of wire is placed in a changing magnetic field. What phenomenon is observed?

A loop of wire is placed in a changing magnetic field. What phenomenon is observed?

Step 1: Understand that a loop of wire is a closed circle made of conductive material.
Step 2: Recognize that a magnetic field is an area around a magnet where magnetic forces can be felt.
Step 3: Know that a changing magnetic field means the strength or direction of the magnetic field is changing over time.
Step 4: Learn about electromagnetic induction, which is the process where a changing magnetic field creates an electric current in a conductor.
Step 5: Realize that when the magnetic field changes around the loop of wire, it induces an electromotive force (EMF) in the wire.
Step 6: Conclude that the phenomenon observed is electromagnetic induction, where the changing magnetic field causes electricity to flow in the loop.

Electromagnetic Induction – The process by which a changing magnetic field induces an electromotive force (EMF) in a conductor.
