A long solenoid with 2.00 x 10³ turns per meter and radius 2.00 cm carries an oscillating current I= 4.00 sin 110zt, where I is in amperes and it 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= (b) What is the direction of this electric field when the current is increasing counterclockwise in the solenoid? clockwise O counterclockwise
