E/m BY HELICAL METHOD TRAINER KIT

Category: Electronics

Model No:IE-302

Experimental Training Board has been designed specifically to determine the value of e/m for an electron by Helical method. The board is absolutely self contained and requires no other apparatus.

Product Description

Electronics emitted from the cathode, accelerated by the anode are deflected by the electric field to give a line on the fluorescent screen. The current carrying solenoid which encloses the Cathode Ray Tube provides the necessary magnetic field for focusing if alternating potential is applied to the plates then the electrons shall experience a transverse alternating force. Under the influence of this potential, we shall get a line on the Cathode Ray Tube screen. The length of the line shall depend on the strength of the applied potential. Now if the longitudinal field because of solenoid is applied, the electron describes a circular path. Motion of the electron in circular path is balanced by the centrifietal forces supplied by the magnetic field.
