Electromagnetic theory
(c) = Use the Biot-Savart law given in part (a) to obtain an expression for the B field generated by a thin current loop of radius, R= (x2 + y2)1/2, along the axis of the loop, R? ро! B(R, Z) = Ź ) (R²+z2; 3/2 The radius of the wire itself is a and it carries current, I. Z R j Hint: the current in the wire loop may be written as I j(x’,y') (-y',x",0). na2R = [8 marks]
(a) According to the Biot-Savart law, the element of magnetic induction field, dB(r), at position, r, that arises from an element of current, j(r'), at position, r', is given by dB(r) = Ho j(r') x (r - r') 410 |r – r'|3 dr'
