Amagnet in the form of a cylindrical rod has a length of 7.30 cm and a diameter of 1.5 cm. it has a uniform magnetization of 5.30 x 103 a/m. what is its magnetic dipole moment in units of jit?

Magnetic dipole moment is 0.0683 J/T.

Explanation:

It is given that,

Length of the rod, l = 7.3 cm = 0.073 m

Diameter of the cylinder, d = 1.5 cm = 0.015 m

Magnetization,

The dipole moment per unit volume is called the magnetization of a magnet. Mathematically, it is given by :

Where

r is the radius of rod, r = 0.0075 m

So, its magnetic dipole moment is 0.0683 J/T. Hence, this is the required solution.

it is the second option.
