The magnetic field in a solenoid is b micro0ni d a


The magnetic field in a solenoid is B = (µ0NI) / d. A circular wire of radius 10 cm is concentric with a solenoid of radius 7 cm and length d = 1 meter, containing 11000 turns. The current increases at a rate of 50 A/s.

What is the emf in the wire?

V

What is the non-Coulomb electric field in the wire?

V/m
