A solenoid of length 25 cm and radius 0.8 cm with 395 turns is in an external magnetic field of 580 G that makes an angle of 50° with the axis of the solenoid. (a) Find the magnetic flux through the solenoid.
(b) Find the magnitude of the emf induced in the solenoid if the external magnetic field is reduced to zero in 1.4 s.
im not sure of any equations to use. i really have no idea how to do a problem like this so if anyone could help me i would appreciate it thanks
