Q41: A long solenoid with turns per meter and radius> 2.00 cm carries an oscillating current I = sin pt, where I is in amperes and t is in sec- onds.
(a) What is the electric field induced at a radius r = 1.00 cm from the axis of the solenoid?
(b) What is the direction of this electric field when the current is increasing counterclockwise in the solenoid?
