5. A loop of wire with dimensions 10.0 cm wide by 50.0 cm long sits 20.0cm to the right of a long straight wire as shown In the figure. The current in the long straight wire I, = 5.0 A and the current In the loop of wire l, = 10.0 A. Find the magnitude and direction of the net force on the loop of wire. 50.0 cm --3 20.0 cm 10.0 em 6. You want to construct a solenold that will have a resistance of 5.0 0 at 20 *C and produce a magnetic field of 4.00 x 102T at Its center when the current through It Is 4.00 A. The solenold is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenold is to be 1.00 cm, determine (a] the number of turns needed and (b) the length of the solenold
