Composition of Magnets Based on composition, there are mainly two types of magnets known as the natural and artificial magnets. Magnet is a material that produces a magnetic field. Magnets can be of various types and thus vary their composition. The natural and artificial magnets are the two broad types of magnets. Natural Magnets Natural [...]
The Science Behind Electromagnets People often associate electromagnets with science fiction or futuristic technology, like trains that hover or large devices that can simulate a black hole. It often surprises a lot of people that electromagnets are quite commonplace and you likely have at least two in your home. The industrial applications for electromagnets are [...]
Round and Rectangular Electromagnets Round and Rectangular Flat-Faced Electromagnets are available in a variety of sizes. Flat-Faced magnets should only be used on flat, smooth material where the entire magnet face is in contact. They can be used in manually operated or automated applications. Magnets listed utilize 12 volt D.C. current (24VDC and 110VDC are [...]
Explanation of the Solenoids Device Types Acting Solenoids Depending on the type of motion cycle, a distinction is made between single, double and reverse acting solenoids. Single acting solenoids are electromagnets in which the movement from the initial position to the end position is effected by electromagnetic force. An external force is required in order [...]
Electromagnetism & Magnetism Applications Magnetism and moving electrons are closely related to each other. The three phenomena pertaining to electromagnetism are: Moving electric charges produce magnetic fields. Magnetic fields exert forces on moving electric charges. Changing magnetic fields in the presence of electric charges cause electrons to flow In 1820, Danish physicist Hans Oersted noted [...]
Magnetic Core A magnetic core consisting of a plastic or ceramic toroid around which is wound a strip of thin magnetic tape possessing a square hysteresis-loop characteristic. A magnetic core is a piece of magnetic material with a high permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as [...]
What Makes a Magnet Stick? The Science Behind Magnets Magnets are a little magical, but mostly they obey the rules of physics. How can you trust the power of your magnets? Learn the science! The fascination with magnets starts early in life, with children performing tiny experiments to see what they can do with the [...]
How Does Temperature Affect Different Magnets? The relationship between magnetic strength and ambient temperature is somewhat complicated. If you are in need of a magnet, however, it is important for you to understand how temperatures affect the strength of different types of magnets before choosing a product. This will allow you to choose the magnet [...]
Working With Magnets in High or Low Temperatures The ambient temperature surrounding your magnets during work impact their strength significantly, but each magnetic material is different. Which magnet works best in your conditions? Temperature and magnetic strength have a turbulent relationship. Some applications require magnets in freezing conditions, while others work in searing heat. Some [...]
Superconducting Magnet A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire has no electrical resistance and therefore can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields [...]
Superconducting Magnet Construction A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation.

Superconducting magnets can produce greater magnetic [...]
The difference between electromagnet and permanent magnet Electromagnets (solenoids) is a kind of electromagnetic equipment, which transforms electric energy into magnetic energy, and then transforms magnetic energy into kinetic energy (electric energy → magnetic energy → kinetic energy). First of all, the core is wound with a conductive winding matching its power. Such a coil [...]
