A wire loop having area 0.606 m2 is placed in a uniform magnetic field with the normal vector of the loop at a 75.1 degree angle to the field. The field has an initial magnitude of 2.91 Tesla and then is increased at a constant rate to 7.97 Tesla in 0.856 seconds. If a current of 0.0980 Amps is measured to flow through the wire during this time, what must the resistance of the wire be in Ohms

The resistance of the wire is is 36.55 ohms.

Induced emf of the coil

The induced emf in the loop is calculated by Faraday's law as follows;

emf = A(B₂- B₁)/t

emf = 0.606 (7.97 - 2.91)/0.856

emf = 3.58 V

Resistance of the wire

The resistance of the wire is calculated by using Ohms law as follows;

emf = IR

R = emf/I

R = 3.58/0.098

R = 36.55 ohms
