Find the magnetic field intensity when the flux density is 8 x 10^-6 Tesla in the medium of air.(a) 6.36(b) 3.66(c) 6.63(d) 3.36I got this question in an online interview.The question is from Magnetic Field Density topic in section Magnetostics of Electromagnetic Theory

Answer»

Right answer is (a) 6.36

The explanation: We how that, B = μH. To get H = B/μ, PUT B = 8 X 10^-6 and μ = 4π x 10^-7. Thus H = 8 x 10^-6/ 4π x 10^-7 = 6.36 units.
