The component of the external magnetic field along the central
axis of a 49 turn circular coil of radius 41.0 cm decreases from
1.90 T to 0.700 T in 3.40 s. If the resistance of the coil is R =
7.50 Ω, what is the magnitude of the induced current in the
coil?

Ω, what is the magnitude of the induced current in the coil?

Induced voltage in a conductor is a function of magnetic field
strength, conductor numbers and :

direction. B) Determine the magnitude of the magnetic field when
these currents are in opposite directions.
