A wire, of length L = 4.1 mm, on a circuit board carries a current of I = 1.96 μA in the j direction. A nearby circuit element generates a magnetic field in the vicinity of the wire of B = Bxi + Byj + Bzk, where Bx = 4.9 G, By = 2.3 G, and Bz = 2.4 G.
a. Calculate the magnitude of the magnetic field B, in gauss, in the vicinity of the wire due to the circuit element.
