Helmholtz Coil

Concept Overview:

1. Production of a uniform magnetic field resulting in a circular beam of electrons
2. Measurement of the charge to mass ratio of the electron

Lecturer Procedure

Step(s) to Follow

1. Turn on coil
2. Wait 30 seconds - unit will perform self test.
3. Adjust voltage to 200V
4. Adjust current until circular beam exists 

Expected Result

For charge to mass ratio:

Measure the diameter of the beam and complete the necessary calculations
