Question

Write S.I unit of magnetic dipole moment.

Answer 1

Hint: Formula of magnetic dipole moment is
$\mu =IA$
In which I is the current flowing which can be expressed in the unit of amperes.
And A is the area of the surface which is basically distance and can be expressed in square meters.

Complete step by step answer:
First of all let us look at what is a magnetic dipole moment.
The magnetic moment is the strength of the magnet and orientation of a magnet .It can be other objects or things which are able to produce magnetic fields. There are so many things around us which are having magnetic dipole moments. Moving charges like electrons, protons and so on can produce magnetic dipole moment. Any electrical current loops are also examples for this. Astronomical objects like planets, moon, stars can also produce magnetic dipole moments. Basically magnetic dipole moment is a vector quantity which means quantity is having both magnitude and direction. Magnetic dipole moment can be defined in terms of torque also. It is the torque an object experiences in the magnetic field.
Magnetic dipole moment can be expressed in the form of equation

$\mu =IA$

In which I is the current flowing which can be expressed in the unit of amperes.
And A is the area of the surface which is basically distance and can be expressed in square meters.
Therefore the S I unit of magnetic dipole moment is expressed in,
Ampere square meter.

Note:
There are several systems of declaring units .So when we are using the S.I unit system, then all the units for the terms in that equation should be taken in S.I units itself. Therefore the S.I unit of magnetic dipole moment is Ampere square meter.
