A solenoid 88.0 cm long has a radius of 2.60 cm and a winding of 2000 turns; it carries a current of 3.60 A.
(a) Calculate the magnitude of the magnetic field inside the solenoid.
(b) Calculate the magnetic field outside the solenoid.
(c) An electron is shot with a velocity 4 x 106 m/s along the axis of the solenoid. What is the magnitude of the magnetic force on the electron?
