Magnetic Moment of Current Loop | Moving Charges and Magnetism Part 2 | Class 12 Physics | JEE 2026

Welcome to Part 2 of the Moving Charges and Magnetism chapter! In this session, we’ll break down the concept of the Magnetic Moment of a Current Loop — a key topic in Class 12 Physics and a frequent favorite in JEE Main 2026.

In this video, you’ll learn:
➜What is Magnetic Moment?
➜Derivation and formula for magnetic moment of a current-carrying loop
➜Direction of magnetic moment using the right-hand rule
➜Applications and real-life examples
➜Conceptual questions + JEE-level practice problems

The concept of the magnetic moment plays a crucial role in the study of magnetism and magnetic materials. It provides valuable insights into the magnetic behavior of substances and their response to external magnetic fields.

The magnetic moment of a current loop is determined by multiplying the magnitude of the current flowing through the loop by the enclosed area.

Mathematically it is given by,
M = I x A
So the unit of magnetic moment is Amp-m2.
