Question

Find the magnetic field intensity due to an infinite sheet of current 5A and charge density of 12j units in the positive y direction and the z component is above the sheet.

(a) -6

(b) 12k

(c) 60

(d) 6

This question was addressed to me by my college director while I was bunking the class.

I need to ask this question from Ampere Law topic in chapter Magnetostics of Electromagnetic Theory

Answer 1

The correct choice is (d) 6

Easy explanation: The magnetic field intensity when the normal component is above the sheet is Hx = 0.5 K, where K = 12. Thus we get H = 0.5 x 12 = 6 units.
