Product Details

RS PRO ATEX Magnet Stick

A non-contact magnetic field detector and solenoid tester, which lights up when the tip is in the presence of a magnetic field. The magnet stick is able to detect a variety of magnetic fields, from alternating current and direct current to permanent strong magnets. The test lamp of your magnet stick lights up immediately and without metallic contact when a magnetic field is present (e.g. an activated coil in a solenoid valve). A small test magnet is also housed in the cap allowing users to test to ensure the article is working correctly for accurate detection. Ideal for testing solenoid valves in pneumatic systems, hydraulics and vehicles, relays with coils can also be tested.

• Automotive relay fault finding
• Air conditioning servicing
• Fault finding
• Testing solenoid valves when servicing oil burners

What is a magnetic field detector?

A magnetic tester or detector such as the Magnet Stick, is an instrument that is able to detect magnetism, they are able to identify magnetic materials or fields.

What is a magnetic field?

It is a vector field and best describes the magnetic influence of electric charge in magnetic materials or relative motion. Measured usually by strength and direction, these vector quantities can be measured in Gauss or units of Tesla in SI units. They are otherwise known as a moving electrical charge often used in electromechanics and engineering within electric motors.
