This preview shows page 7 - 10 out of 10 pages.

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. See Solution on the next page Phys.201 Ch30 Dr.Hikmat A. Hamad Page 8 39. A long solenoid that has 1 000 turns uniformly distributed over a length of 0.400 m produces a magnetic field of magnitude 1.00 x 10-4T at its center. What current is required in the windings for that to occur? 45. A cube of edge length , 5 2.50 cm is positioned as shown in Figure P30.45. A uniform magnetic field given by 𝐵 = (5 ? + 4 ? + 3 ? ) exists throughout the region. (a) Calculate the magnetic flux through the shaded face. (b) What is the total flux through the six faces? 46. Consider the hemispherical closed surface in Figure P30.46. The hemisphere is in a uniform magnetic field that makes an angle θ with the vertical. Calculate the magnetic flux through (a) the flat surface S1 and (b) the hemispherical surface S2. #### You've reached the end of your free preview.
