7. A solenoid with ends marked A and B is suspended by
a thread so that the core can rotate in the horizontal
plane. A current is maintained in the coil so that the
electrons move clockwise when viewed from end A
toward end B. How will the coil align itself in Earth's
magnetic field?

Ahuge (essentially infinite) horizontal nonconducting sheet 10.0 cm thick has charge uniformly spread over both faces. the upper face carries +95.0 nc/m2 while the lower face carries -25.0 nc/ m2. what is the magnitude of the electric field at a point within the sheet 2.00 cm below the upper face? (ε0 = 8.85 × 10-12 c2/n · m2)
