Question
current-carrying wires are wrapped around the square solenoid of side a, length L, and n turns per meter. Assume the current runs clockwise (looking down on the coil).a) At the geometric center of the cavity inside the solenoid: the magnetic field
points away from you, into the page
points toward you, out of the page
points upward
points downward
points to the right
is approximately zero
points to the left
b) Suppose we put current I through the coil, and the magnetic field at the center of the cavity is B. If we now double three quantites: side a, number of turns per meter .n and length L, the new mangetic field at the center of the cavity will be
