Problem: Two long parallel wires are separated by 4.0 cm. One of the wires carries a current of 20 Amp and the other carries a current of 30 A. Both currents are in the same direction.
Part A: Determine the magnitude of the magnetic force on a 2.0m length of the wire carrying 30 A of current.
Part B: What is the direction of the force?
Thanks in advance that solve the above problem.
