e/m Apparatus - code: 4508.00

Apparatus for measuring the ratio e/m of an electron in a magnetic field. When a charged particle moves in a magnetic field it is subjected to the so-called Lorentz's force that exerts a centripetal acceleration on the particle. The intensity of the force depends on the ratio of charge to the mass. The e/m apparatus can measure such a quantity for the electron relating the radius of curvature to the ratio using the Lorentz's formula. With e/m Apparatus, results are clearly visible and the experiment becomes stimulating and interesting, making it an ideal way to begin discovering the modern physics.
