Types of Magnets

We are one of leading Manufacturers, Exporters and Suppliers of Electro Magnets from India. The most fundamental type of electromagnet is a simple segment of copper wire The amount of magnetic field generated depends upon the amount of electrical current that flows through the wire. In order to concentrate the magnetic field generated by a wire, it is commonly wound into a coil, where many segments of wire sit side by side.

A coil forming the shape of a straight tube, a helix (similar to a corkscrew) is called a solenoid; a solenoid that is bent into a donut shape so that the ends meet is a toroid. Much stronger magnetic fields can be produced if a "core" of ferromagnetic material (commonly soft iron) is placed inside the coil. The core concentrates the magnetic field that can then be much stronger than that of the coil itself.

Ferrite Magnets are sintered permanent magnets and are composed of Barium or Strontium Ferrite. This class of magnets has a good resistance to demagnetization and has the popular advantage of having a low cost. These are very hard and brittle, and need special machining techniques and should be machined in an unmagnified state.

Our unit is equipped to machine these materials as per required specifications. Having a low cost, Ferrite Magnets have a wide application area, ranging from motors and loudspeakers to toys and crafts. These form the most extensively used permanent magnets today.
