A long solenoid with 1.50 x 10³ turns per meter and radius 2.00 cm carries an oscillating current I = 7.00 sin 90πt, where I is in amperes and t is in seconds. (a) What is the electric field induced at a radius r = 1.00 cm from the axis of the solenoid? (Use the following as necessary: t. Let E be measured in millivolts/meter and t be measured in seconds.) E = Ne (b) What is the direction of this electric field when the current is increasing counterclockwise in the solenoid? clockwise counterclockwise
