Lesson: The Magnetic Field due to a Current in a Circular Loop of Wire Physics • Third Year of Secondary School

Join Nagwa Classes

Attend live Physics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to calculate the magnetic field produced by a current in a circular loop of wire.

Students will be able to

use the formula to find the magnitude of the magnetic field strength at the center of a current-carrying loop of radius ,
use for many loops,
recognize that as the radius of the loop gets larger, the magnetic field strength at the center gets weaker,
use the right-hand screw rule to determine the direction of the magnetic field through the loop.
