Magnetic Switches

A magnetic switch is an electrical switch designed to make contact or break contact within a magnetic field. While a light switch is what we''d consider as a mechanical switch, magnetic [electrical] switches are specially designed to function in applications when a traditional mechanical switch isn''t efficient or safe. Neodymium (NdFeB ...

Electropermanent magnet

An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) ...

Magnet Switch MRK

The MRK Magnetic Switch, equipped with a reed contact, is switched by the approach of a permanent magnet. The contact surrounded by protective gas reliably reports the position of moving parts. In a bistable version, it has a stay-put latching effect and remains in the switching position until a magnet passes in the opposite direction.

Permanent Magnet Generators | How it works, Application

Permanent magnet generators offer several advantages over traditional generators. These include increased efficiency, reduced operational noise, and decreased size and weight for the same output power. The efficiency gains are particularly significant because the PMGs do not require any external power source for magnetization, reducing energy loss.

How Reed Switches are used with a Permanent Magnet

shown for a magnet passing in parallel to Reed Switch and being affected by the center magnetic lobe.) Also, for parallel motion, if the magnet and switch are close enough, parallel motion can create three closures and openings as demonstrated in Figure #25. Passing the magnet by the Reed Switch farther away, one closure and opening will occur.

6.5: Permanent Magnet Devices

Most permanent magnets have magnetic flux densities B less than one Tesla (10 4 gauss), so a magnet this powerful with an area A = 10 cm 2 (~the size of a silver dollar) would therefore apply an attractive force AF = 0.001×1 2 /2×4π10-7 ≅ 400N (~100 pound force). A more typical permanent magnet the same size might attract a steel surface with only a 10–20 pound …
