Question: It is proposed to store 1.00 kW h = 3.60 X 106 J of electrical energy in a uniform magnetic field with magnitude 0.600 T.

It is proposed to store 1.00 kW ∙ h = 3.60 X 106 J of electrical energy in a uniform magnetic field with magnitude 0.600 T.
(a) What volume (in vacuum) must the magnetic field occupy to store this amount of energy?
(b) If instead this amount of energy is to be stored in a volume (in vacuum) equivalent to a cube 40.0 cm on a side, what magnetic field is required?
