The component of the external magnetic field along the central axis of a 50 turn coil of radius 4.0 cm increas?
The component of the external magnetic field along the central axis of a 50 turn coil of radius 4.0 cm increases from 0 T to 1.8 T in 4.2 s.
If the resistance of the coil is 2.8 , what is the magnitude of the induced current in the coil? <-- in Amps
Thank you for your help.
Area A = pi*r^2 = 5.02654824574367E-03 m^2
From Faraday’s law (ref.):
V = N*d(BA)/dt = NA*dB/dt = 0.107711748123079 V
I = V/R = 3.84684814725282E-02 A
