MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER In the figure below, the current in the long, straight wire is I, = 6.50 A, and the wire lies in the plane of the rectangular loop, which carries 15.0 A. The dimensions shown are c = 0.100 m, a = 0.150 m, and { = 0.450 m. Find the magnitude and direction of the net force exerted by the magnetic field due to the straight wire on the loop. magnitude N direction ---Select--- C -a- Need Help? Read It Master It 10.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER It is desired to construct a solenoid that will have a resistance of 5.75 9 (at 20 C) and produce a magnetic field of 4.00 x 10-2 T at its center when it carries a current of 3.75 A. The solenoid is to be constructed from copper wire having a diameter of 0.500 mm. If the radius of the solenoid is to be 1.00 cm, determine the following. (The resistivity of copper at 20 C is 1.7 x 10-8 0 . m.) (a) the number of turns of wire needed to build the solenoid turns (b) the length the solenoid should have cm Need Help? Read It 11.
