A particular solenoid (50 cm long with 2000 turns of wire) carries a current of 0.70 A
Question:
A particular solenoid (50 cm long with 2000 turns of wire) carries a current of 0.70 A and is in vacuum. An electron is shot at an angle of 10° to the solenoid axis from a point on the axis.
(a) What must be the speed of the electron if it is to just miss hitting the inside of the 1.6-cm-diameter solenoid?
(b) What is then the pitch of the electron’s helical path?
