Force on Moving Charge: Magnetic Fields & Forces
Force on Moving Charge: Magnetic Fields & Forces
Purpose
To demonstrate the force on charges (and subsequent change in the motion of the
charges) moving perpendicular
to a magnetic field.
Description
A beam of free electrons is bent into a circular/ spiral path by large Helmholtz coils.
- To observe the effect of the external magnetic field on the moving electrons,
vary the strength of the current in the Helmholzt coils and the initial
direction of the electron beam.
Equipment
e/m Tube, power supply and lead wires
