Answer 2

The correct answer among all the option is (iv) 313 X 106​.

Explanation:

• The energy stored per unit volume in a magnetic field of flux density is given by 1.373 Wb/sq. m is 500 J then it's relative permeability is 313 X 106​.
• The magnetic energy stored per unit volume is equal to pBH J/m3.
• Hence, the correct answer is option iv i.e 313 X 106​.
