Electromagnetic Transmissions Solenoids Holding Magnets Solenoids for simple operation Single-acting solenoids are for common applications. The magnetic field delivered by the coil upon power-up attracts the core. Then, the nucleus becomes free again in the absence of current. They are thus available in different designs, folded sheet, square profiled, machined in the mass. Solenoids for [...]

Selecting the Right Electromagnet There are many variables that must be considered in the selection of a proper magnet. To help you get the best magnet for your application, we should have the following information: Surface of the Work Is it scaly, rough, flat, machined or of irregular shape? Size of the Work Give thickness, [...]
Electromagnet or solenoid are general terms for all types of electromagnetic actuators. Basically, electromagnets or solenoids are devices that generate a magnetic field by means of an energized coil, guiding it through suitable iron parts with air gap. Here, magnetic poles are created inbetween which a magnetic force of attraction, the magnetic force, prevails. If [...]
Electromagnetic Radiation Definition Electromagnetic radiation is self-sustaining energy with electric and magnetic field components. Electromagnetic radiation is commonly referred to as "light", EM, EMR, or electromagnetic waves. The waves propagate through a vacuum at the speed of light. The oscillations of the electric and magnetic field components are perpendicular to each other and to the [...]
The Relationship Between Electricity and Magnetism Together, these two phenomena form the basis for electromagnetism Electricity and magnetism are separate yet interconnected phenomena associated with the electromagnetic force. Together, they form the basis for electromagnetism, a key physics discipline. Key Takeaways: Electricity and Magnetism Electricity and magnetism are two related phenomena produced by the electromagnetic [...]
Can't get enough of hands-on electromagnetic experiments? We have some more ideas for you to try: What is the magnetic power of a single coil wrapped around a nail? Of 10 turns of wire? Of 100 turns? Experiment with different numbers of turns and see what happens. One way to measure and compare a magnet's [...]
Electromagnets All Around Us Many electromagnets have an advantage over permanent magnets because they can be easily turned on and off, and increasing or decreasing the amount of electricity flowing around the core can control their strength. Modern technology relies heavily on electromagnets to store information using magnetic recording devices. When you save data to [...]
The History of Electromagnets The relationship between electricity and magnetism wasn’t thoroughly studied until 1873 when physicist James Maxwell observed the interaction between positive and negative electrical charges. Through continued experimentation, Maxwell determined that these charges can attract or repel each other based on their orientation. He was also the first to discover that magnets [...]
How Electromagnets Work What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. [...]
How to Make a Super Power Electromagnet Building a super-power electromagnet is really no different than building a simple nail-and-copper-wire kind. The difference is that you want a better core, more power and more dense windings. To that end, this project uses a ferrite rod instead of an iron nail, a power supply instead of [...]

The Difference Between Magnetic Beads and Inductors The inductor is an energy storage component and the magnetic beads are energy conversion (consumption) devices. Inductors are mostly used in power supply filter loops, focusing on suppressing conducted interference; magnetic beads are mostly used in signal loops, mainly for EMI. Magnetic beads are used to absorb ultra-high [...]
