1. Two parallel wires are separated by a distance of 5.00 cm. Each wire carries a current of 2.69 A in the same direction.
(a) Find the magnitude of the force per unit length exerted by one of the wires on the other. Is the force attractive or repulsive?
(b) If the currents flow in opposite directions, find the magnitude of the force per unit length exerted by one of the wires on the other. Is the force attractive or repulsive
2. What current must be passing through a 0.0700 H inductor so that it stores 0.600 J of energy?
