Question
1) As a hole is dug into the Earth, the temperature rises 1.52°C for every 50.0 m below the surface. At what depth will iron fail to remain magnetic? (Assume that the linear relation holds true for a while and that the surface temperature is 20.0°C.)

3)
A parallel-plate capacitor is charged at a constant rate by a current of 1.8 A. That is, I = dQ/dt = 1.8 A. The area A of each plate is 0.0023 m2, and the plates are very close together. What is the displacement current between the plates?
4)
A charged object is enclosed by two Gaussian surfaces: a sphere of radius 0.240 m, and a cube where each edge has length 0.240 m. If the electric flux through the surface of the sphere is 9.22
One plate of a charging parallel-plate capacitor is shown (this is the same capacitor as in the sample problem in the text). The radius of the capacitor plate is 0.150 m. Find the strength of the magnetic field at this distance from the center of the capacitor.3)

Explanation / Answer
1) (770 - 20)/1.52 * 50 = 2.47*104 m
2) B*2*?*r = ?0*dE/dt*?r2 , so B = ?0*dE/dt*r/2 = 0.0133 T
3) = 1.8 A
4) = 9.22
