In this problem, you will use Lenz's law to explore what happens when an electromagnet is activated a short distance from a wire loop. You will need to use the right-hand rule to find the direction of the induced current. When the switch is open, which of thefollowing statements about the magnetic flux through the wire loopis true? Assume that the direction of the vector area of the wireloop is to the right.
a. There is nomagnetic flux through the wire loop.
b. There is apositive flux through the wire loop.
c. There is anegative flux through the wire loop.

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)
