Find the magnetic field when the magnetic vector potential is a unit vector.(a) 1(b) -1(c) 0(d) 2I have been asked this question during an internship interview.My question is from Magnetostatic Properties topic in chapter Magnetostics of Electromagnetic Theory |
Answer» RIGHT option is (c) 0 Easiest explanation: We KNOW that H = -Grad(V), where is a UNIT vector. The gradient of a constant/unit vector will be zero. Thus the MAGNETIC field INTENSITY will be zero. |
