Item no.: P2510200

Principle

Electrons are accelerated in an electric field and enter a magnetic field at right angles to the direction of motion. The specific charge of the electron is determined from the accelerating voltage, the magnetic field strength and the radius of the electron orbit.

Tasks

Determination of the specific charge of the electron (e/m0) from the path of an electron beam in crossed electric and magnetic fields of variable strength.
