Find the magnetic field intensity at the centre O of a square of the s

1.	Find the magnetic field intensity at the centre O of a square of the sides equal to 5m and carrying 10A of current.(a) 1.2(b) 1(c) 1.6(d) 1.8This question was addressed to me by my school principal while I was bunking the class.This key question is from Biot Savart Law in portion Magnetostics of Electromagnetic Theory
Answer» Correct answer is (d) 1.8 The best explanation: The magnetic FIELD is given by H = 4I/√2πω. PUT I = 10 and ω = 5m. THUS H = 4 x 10/√2π(5) = 1.8 UNIT.
