Solve the all parts of given question:
Question: Two long straight wires are parallel and carry currents of I1 = 6.20 A and I2 = 4.30 A in opposite directions. The wires are separated by a distance of 10.0 cm.
Part A: Determine the magnitude of the force exerted by one wire on the other.
Part B: Is the force attractive or repulsive?
I need help to find the magnitude of the force exerted by one wire on the other.
