HOI The strength of the magnetic field B at a distance r from a straight conductor carrying a current I is given by the expression B = 2πr where μo is the permeability of free space with the value 4 x 10-7 NA-2. Two long straight wires are lined up parallel to one another at a separation of 0.22 m. Currents of 4 A and 2 A flow through the wires, both in the same direction. Calculate the absolute value of the magnetic field strength due to the two wires at a point P on the mid-plane between them. Give your answer in micro Tesla (µT, 10-6). Answer: Choose... +
