Chapter 25, Problem 30MCQ
A device called a flip coil can be used to measure the earth’s magnetic field. The coil has 100 turns and an area of 0.010 m2. It is oriented with its plane perpendicular to the earth’s magnetic field, then flipped 180° so the field goes through the coil in the opposite direction. The earth’s magnetic field is 0.050 mT, and the coil flips over in 0.50 s. What is the average emf induced in the coil during the flip?
A. 0.050 mV
B. 0.10 mV
C. 0.20 mV
D. 1.0 mV

A small conducting spherical shell with inner radius aa and outer radius bb is concentric with a larger conducting spherical shell with inner radius c and outer radius d (Figure 1). The inner shell has total charge +2q, and the outer shell has charge −2q. Calculate the magnitude of the electric field in terms of q and the distance rr from the common center of the two shells for r<a. Calculate the magnitude of the electric field for a<r<b. Calculate the magnitude of the electric field for b<r<c.
A cube has sides of length L = 0.800 m . It is placed with one corner at the origin as shown in the figure. The electric field is not uniform but is given by E→=αxi^+βzk^, where α=−3.90 and β= 7.10. What is the sum of the flux through the surface S5 and S6? What is the sum of the flux through the surface S2 and S4? Find the total electric charge inside the cube.
