An electromagnet is a type of magnet that is composed of a battery and iron wire that uses electric current in order to generate a magnetic field. Electromagnet The magnetic field is generated when the electric current passes through a wire, and the field dissipates when the current stops. The primary function of electromagnets is [...]

Electric Hysteresis Brakes

Electric Hysteresis Brakes These brakes utilize an electromagnet to generate drag torque Drag torque is dependent on input current and independent of slip speed, a constant current power supply such as our MPP24 must be used Torque on each unit can be adjusted to any value between bearing drag (~0) and the max torque indicated [...]

What you choose magnetic disc type?

Which type of magnetic disc should you choose? magnetic disc type - The basic magnetic disc is the most universal in terms of use compared with the other magnetic discs. It is the best type to be used as the magnetic component in a range of different items such as machinery, or even the back [...]


Electromagnets are a non-permanent magnets that produced magnetic field. The magnetic field is created by a flow of an electric current through the coil. The magnetic field disappears when the current ceases (or in the caseelectromagnets of a permanent electromagnet, the magnetic field is present until a current is applied). Electromagnets As a [...]


Rectangular Electromagnet are available in four standard sizes. These magnets provide positive holding power and high responsiveness in numerous manual or automatic applications. Controlled by a remote IMI power supply, rectangular electromagnets are available in 24VDC, *110VDC and 120VAC models. Our Electromagnets offer On/Off capability and can be controlled in an automated sheet metal handling [...]

How Speakers Work

How Speakers Work - Making Sound: Speaker Magnets When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and attached diaphragm back and forth. How Speakers Work So how does the [...]

How to Use Electromagnetic Locks

Here are some suggestions and recommendations for the installation and functionality testing to Use Electromagnetic Locks: electromagnetic-lock-feature-illustration Use Electromagnetic Locks - The electromagnetic lock requires a face to face fitting as shown in the illustration. Otherwise, the holding force will decrease (direction of hydraulic press pull must be collinear). electromagnetic-lock-and-armature-plate Install [...]

Electromagnetic Lock

Electromagnetic Lock An electromagnetic lock, magnetic lock, or maglock is a locking device that consists of an electromagnet and an armature plate. There are two main types of electric locking devices. Locking devices can be either "fail safe" or "fail secure". A fail-secure locking device remains locked when power is lost. Fail-safe locking devices are [...]

How does an electromagnetic lock work?

How does an electromagnetic lock work? electromagnetic lock work - An electromagnetic lock creates a magnetic field when energized, causing an electromagnet and armature plate to become attracted to each other strongly enough to keep a door from opening, according to HangSeng Magnetech Inc. most cases, the armature plate is on the edge of the door, [...]

Brush DC Motor Drivers

Brush DC Motor Drivers - Brush DC motors are the most widely used drivers due to their low cost and simple drive control options. Typical brush DC motors consist of a rotating electromagnet surrounded by a permanent magnet. Rotational torque is produced by the interaction of the magnetic fields and continuous rotation is produced by [...]

Magnetic Propulsion and the Final Frontier

magnetic-propulsion-space-pixabay With help from magnets, we may be able to explore farther and deeper into the final frontier than ever before. This may sound like science fiction, but scientists are already experimenting with electromagnetic propulsion as a possible alternative to chemical launches. So, how does electromagnetic propulsion work? When an electromagnet is cooled [...]

World’s Most Powerful Magnet Under Construction

Multiply the magnetic field strength of a refrigerator magnet by 2 million and you'll be in the ballpark of the strength of the magnet that researchers at the National High Magnetic Field Laboratory, based near Florida State University in Tallahassee, are trying to create. When completed later this year, the pulsed electromagnet, located at the [...]

Super magnet to not destroy itself

Researchers at Los Alamos National Laboratory, in New Mexico are in the process of creating a pulsed electromagnet that will reach 100 tesla. Greg Boebinger, director of the project, says that these forces are “equivalent to the explosive force of 200 sticks of dynamite packed into a volume of space the size of a marble.” [...]

What are Some Uses for Industrial Magnets?

Industrial magnets come in a wide range of types, shapes, sizes and strengths. They are utilized across a diverse spectrum of industries for an equally diverse set of purposes. Particular uses of industrial magnets depend upon particular requirements. Industrial magnets for dockside-derrick-crane The Magnetic Materials Producers Association (MMPA) and the Magnetic Distributors and [...]

Electromagnets vs Permanent Magnets

Permanent Magnets vs Electromagnets Electromagnets and Permanent Magnets: What are the Differences? An electromagnet is made from a coil of wire which acts as a magnet when an electric current passes through it. Often an electromagnet is wrapped around a core of ferromagnetic material like steel, which enhances the magnetic field produced by [...]
