Magnetic Effect Cathode Ray Tube
Product Code : JA-APE-9393
The Magnetic Effect Cathode Ray Tube (SKU JA-APE-9393) is the Crookes tube that shows electrons carry an electric charge and lets students work out which sign of charge it is. With this magnetic effect Crookes tube, the electron beam is deflected when a magnetic field is applied, and the direction of deflection, read with the left-hand rule, shows that the moving particles are negatively charged. It is one of four Crookes tubes for demonstrating the properties of electrons.
Specifications
The tube is a highly evacuated, fragile glass Crookes tube; mounted in its holder, it is run from a variable 2-12 V DC supply and a high-voltage DC source through two sets of connecting leads, with a magnet used to apply the field.

Demonstrations with the magnetic effect tube
Bringing a magnet up to the tube bends the electron beam, which is direct evidence that cathode rays are charged particles, and the direction of bending lets students deduce that the charge is negative.
- Deflecting an electron beam with a magnetic field
- Determining the sign of the charge on electrons from the direction of deflection
- Applying the left-hand rule to a beam of moving charges
- Comparing magnetic and electrostatic deflection with the Electrostatic Deflection tube

Frequently asked questions
What does the magnetic effect tube show?
It shows that electrons carry a charge and makes it possible to determine which charge.
What else is needed to operate it?
A variable 2-12 V DC power supply, a source of high-voltage DC and two sets of connecting leads, one with banana plugs and one with alligator clips; a magnet is used to deflect the beam.
How should it be handled?
As a highly evacuated glass tube it is fragile; handle it carefully and mount it in its holder before any connections are made.
What should a quotation request include?
