Question: What is the effect of increasing the radius of a circular loop on the magnetic field at its center?

Options:

Correct Answer: Decreases

Solution:

The magnetic field at the center of a circular loop decreases as the radius increases.

What is the effect of increasing the radius of a circular loop on the magnetic field at its center?

Step 1: Understand that a circular loop carries an electric current.
Step 2: Know that the magnetic field is created around the loop due to this current.
Step 3: Recognize that the strength of the magnetic field at the center of the loop depends on the radius of the loop.
Step 4: Realize that as the radius of the loop increases, the distance from the current to the center also increases.
Step 5: Understand that a greater distance means the magnetic field strength decreases.
Step 6: Conclude that the magnetic field at the center of the loop decreases as the radius increases.
