Acoil 3.95 cm radius, containing 520 turns, is placed in a uniform magnetic field that varies with time according to b=( 1.20×10−2 t/s )t+( 3.45×10−5 t/s4 )t4. the coil is connected to a 560-ω resistor, and its plane is perpendicular to the magnetic field. you can ignore the resistance of the coil.
a-)find the magnitude of the induced emf in the coil as a function of time.

find the magnitude of the induced emf in the coil as a function of time.

e= 1.07×10−2 v +( 1.05×10−4 v/s3 )t3
e= 3.36×10−2 v +( 8.26×10−5 v/s3 )t3
e= 3.36×10−2 v +( 3.30×10−4 v/s3 )t3
e= 1.07×10−2 v +( 3.30×10−4 v/s3 )t3
b-)what is the current in the resistor at time t0 = 5.25 s ?
