Help me figure it out plz
Consider the wire below in an external, constant magnetic field of 0.0100 T. The wire has an expanding radius given by r = r_0e^beta t where r_0 = 3.00 cm and beta = 0.250 s^-1. (a) What is the induced electric field in the wire at t = 2.00 s? (b) If the induced current is in the direction given below, what is the direction of the external magnetic field?
