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

Options:

Correct Answer: Electromagnetic induction

Solution:

This is an example of electromagnetic induction, where a changing magnetic field induces an electromotive force (EMF) in the loop of wire.

A loop of wire is placed in a changing magnetic field. What phenomenon is this an example of?

Step 1: Understand what a loop of wire is. It is simply a piece of wire shaped into a circle.
Step 2: Learn about magnetic fields. A magnetic field is an area around a magnet where magnetic forces can be felt.
Step 3: Know that a changing magnetic field means that the strength or direction of the magnetic field is changing over time.
Step 4: Recognize that when the magnetic field around the loop of wire changes, it can create an electric current in the wire.
Step 5: This process of generating electric current from a changing magnetic field is called electromagnetic induction.

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