Homework Statement



A solenoid has a radius of 2.10 cm and 1180 turns per meter. Over a certain time interval the current varies with time according to the expression I = 1.30t, where I is in amperes and t is in seconds. Calculate the electric field 4.65 cm from the axis of the solenoid

I think that should be the Magnetic Field intensity that your looking for.

I believe they are probably asking for the induced electric field caused by the changing magnetic field.

Hello, MelanieB.

I'm afraid the rules here at the forum require you to show some effort at a solution.

Can you think of any laws or concepts that will help solve this problem?
