Physics II Chapter 30: Sources of Magnetic Fields Fall, 2015 5. ( points) In Figure, the current in the long, straight wire is I 1 = 5 . 00 A and the wire lies in the plane of the rectangular loop, which carries a current I 2 = 10 . 0 A . The dimensions in the figure are c = 0 . 100 m, a = 0 . 150 m , and , l = 0 . 450 m . Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire.

Physics II Chapter 30: Sources of Magnetic Fields Fall, 2015 6. ( points) Four long, parallel conductors carry equal currents ofI= 5.00A. Figure is anend view of the conductors. The current direction is into the page at points A and Band out of the page at points C and D. Calculate (a) the magnitude and(b) the direction of the magnetic field at point P, located at the center of the square ofedge length ,l= 0.200m. Page 6/15

Physics II Chapter 30: Sources of Magnetic Fields Fall, 2015 7. ( points) A long, cylindrical conductor of radius R carries a current I as shown in Figure. The current density J , however, is not uniform over the cross section of the conductor but rather is a function of the radius according to J = br , where b is a constant. Find an expression for the magnetic field magnitude B (a) at a distance r 1 < R and (b) at a distance r 2 > R , measured from the center of the conductor. Page 7/15
