MCQPhysics

NCERT · Class 12 · Physics · Magnetism and MatterThe SI unit of magnetic dipole moment is:

Step-by-Step Solution

The magnetic dipole moment $M$ is given by the product of current and area ($M = I \cdot A$). The SI unit of current is Ampere (A) and area is square meter ($\text{m}^2$). Therefore, the SI unit of magnetic dipole moment is Ampere-meter squared ($\text{A m}^2$). It is also equivalent to Joule per Tesla ($\text{J/T}$).
