Two circular poles of the electromagnet, facing each other, both have a radius of R=0.1 m. The electromagnet is suddenly disconnected from its power source, and magnetic field decreases at a rate of 2.0 x 104 T/s. What is the induced electric field in the plane located between the poles of the electromagnet for r1=0.05 m and r2=0.3 m? (Add electric field to the drawing).
