What Is Electromagnetic Lock and How It Works? What Is Electromagnetic Lock? An electromagnetic lock, magnetic lock, or maglock, is a locking device that consists of an electromagnet and an armature plate. It is a magnet that is created when an electrical current is passed through a solenoid (coiled wire wrapped around a metal core). [...]
An Efficient and Optimal Moving Magnet Actuator for Active Vibration Control Abstract: The need for fuel economy and emission restriction has led OEMs to put emphasis on different strategies which allow effective improvements in that field (engine downsizing, cylinder deactivation …). These new applications imply significant vibration increase, created by the engine and transmitted to [...]
ELECTROMAGNETS / ELECTRIC HOLDING MAGNETS (EM) Electromagnets or electric holding magnets develop their high attraction force towards magnetic materials when they are energized. The applications are manifold - wherever ferrous parts have to be fixed during processing or assembly, or ferrous parts have to be attracted or transported. However, electromagnets are most commonly used as [...]
Electro Holding Magnet – Things You Need to Know What Is A Holding Electromagnet? Holding electromagnets are used to attract and hold ferromagnetic pieces. The maximum force efficiency is achieved with the piece to be hold above the attraction’s face and in direct contact with both poles (outside pole and inside pole). How Does A [...]
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 [...]
Energise to Hold Electromagnets / standard Electromagnets / Solenoid/Electromagnet Electrical current is required to turn the magnet ON. Power is removed to turn the magnet OFF. Pull force conversion (approximate): 1kg = 10N = 2.2lb. The outer shell of the electro magnet is a sturdy bright nickel plated cylinder, passivated with body mounting. Designed for [...]

TYPES OF HOLDING MAGNET Electromagnetic holding magnets: The ferromagnetic part is held in place on the holding magnet’s attraction surface when power is supplied to the coil. When the holding magnet is not powered, the electromagnetic force [...]
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 [...]
How are magnetic separators used in the industrial food production? Magnetic separators have become an indispensable aid for industrial food production. They are incredibly versatile and guarantee that the product will be clean, free of impurities, residues and that it will leave the production process with the highest quality. It is important to know that [...]
The Pros and Cons of Alnico Magnets | Are Alnico Magnets Right for Your Job? For a while, alnico was the strongest permanent magnet available. They’re still widely used today in motors, sensors, bearings and more. Find out if they’re right for your job here. Alnico magnets are used less commonly than stronger, rare earth [...]
Electromagnetic Induction While Oersted’s surprising discovery of electromagnetism paved the way for more practical applications of electricity, it was Michael Faraday who gave us the key to the practical generation of electricity: electromagnetic induction. Faraday discovered that a voltage would be generated across a length of wire if that wire was exposed to a perpendicular [...]
Neodymium Speaker Magnets Explained In this article, you will meet a component that perhaps doesn’t get the exposure that it should – the magnet. While each speaker driver is made up of two magnets – an electromagnet and a natural/permanent magnet – the focus will primarily be on the latter. To reproduce sound through a [...]
Why Headphones Have Magnets Inside Music has been around since the beginning of time, but now can be enjoyed in more ways than one ever believed possible. The advancements in headphones have been rapidly increasing from basic over-ear headphones to small, wireless air pods. Purchasing new headphones may lead you to question exactly how these [...]
Robotic Assembly Gripper Magnets With magnetic grippers, you automatically pick up flat steel products or sheets up to 10 mm thick. They are quick and easy to switch, and specially designed for transferring, placing or positioning using a robotic arm. There are different types of robot end effectors. The most common are pneumatic grippers, because [...]
Can unmagnetized steel be magnetized? Yes, all that is necessary is to line up the free electrons in all the atoms in a sample of steel or iron in the same direction. One way of magnetizing steel is to wrap the electric wire around the steel multiple times and then run a current through the [...]
Two Advantages of Electromagnet Over Permanent Magnet Magnets come in two main types: permanent magnets and electromagnets. As its name suggests, a permanent magnet is always magnetized -- think of a kitchen magnet that stays stuck to a refrigerator door for years. An electromagnet is different; its magnetism works only when powered by electricity. Although [...]
Electro Circular Magnets EHRP-ND electro-permanent magnets consist of a circular permanent-magnetic adhesive system and from an excitation winding permitting neutralized in the ON state, the magnetic field to the adhesive surfaces and thus the removal or withdrawal of the workpiece. Because of the permanent-magnetic character of EHRP-ND round magnets these are preferably used where long [...]
