e/m Apparatus EM-4N

SAVE WITH THE E/M APPARATUS + POWER SUPPLY COMBO DEAL!

Introducing our popular e/m Apparatus! Its body is made of durable high quality black acrylic resin. The e/m Apparatus allows students to clearly observe the effects of electric and magnetic fields on an electron stream. This compact instrument provides students a dramatic and visually pleasing experience. The large orbital electron path is circular and Helmholtz coils are integrated.

The beam has a built-in engraved glass rod with a scale along the central axis. This eliminates parallax when taking diameter readings of the electron orbit. You can observe the entire experiment through the front view hole or rear sliding panel.
