1.	Calculate the magnetic energy when the magnetic intensity in air is given as 14.2 units(in 10^-4 order)(a) 1.26(b) 2.61(c) 6.12(d) 1.62I got this question by my college professor while I was bunking the class.Asked question is from Magnostatic Energy in chapter Magnetostics of Electromagnetic Theory
Answer» The CORRECT option is (a) 1.26 Easiest explanation: The MAGNETIC ENERGY is given by E = 0.5 μ H^2. PUT H = 14.2 and in air μ = 4π x 10^-7, we get E = 0.5 x 4π x 10^-7 x 14.2^2 = 1.26 x 10^-4 UNITS.
