Question

3) Three long parallel conductors carry equal currents of I= 5 Amperes. The wires are separated by a neighboring wire from a distance of a = 20 cm. a a а i) Find the magnitude and direction of the magnetic field in the center of the equilateral triangle formed by the three wires. (10 pts) ii) Find the net force per unit length exerted on the bottom left wire due to the other two wires. (10 pts) iii) Find the magnitude and direction of the magnetic field a distance R away from the three wires where R >> a. (5 pts)
