It is proposed to store 1.00kw⋅h=3.60×106j of electrical energy in a uniform magnetic field with magnitude 0.550 t . what volume (in vacuum) must the magnetic field occupy to store this amount of energy?

Explanation:

Given that,

Magnetic field strength, B = 0.55 T

Energy stored,

To find,

The magnetic field occupy to store this amount of energy.

Solution,

We know that the magnetic energy per unit volume in the magnetic field is given by :

So, the volume in the vacuum is . Hence, this is the required solution.
