Given the magnetic field is 2.4 units. Find the flux density in air(in 10^-6 order).(a) 2(b) 3(c) 4(d) 5I have been asked this question in an internship interview.My doubt is from Magnetic Field Intensity topic in portion Magnetostics of Electromagnetic Theory

Answer»

Right ANSWER is (b) 3

Easy explanation: We know that B = μH. On SUBSTITUTING μ = 4π X 10^-7 and H = 2.4, we get B = 4π x 10^-7 x 2.4 = 3 x 10^-6 UNITS.
