Magnetic Field Lines of Pot Magnet As for the term "pot magnet", many people may have heard for the first time that the pot magnet is a kind of magnet wrapped in a steel shell and shaped like a pot, so we call it pot magnet (cup magnet), also called magnetic component. Through magnetic circuit [...]
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 [...]
TECHNICAL EXPLANATIONS FOR ELECTROMAGNETIC HOLDING MAGNETS Our products conform to the production standard DIN VDE0580 and are RoHS-compliant. 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 [...]
Some Introduction About Speaker Magnets Speakers are a type of transducer which can transfer the electric signal to the acoustic signal. The sound quality of the speaker is largely depended on the speaker magnets. Speakers can be classified to internal magnetic type and external magnetic type according to the magnetic circuit structure. Speakers also can [...]
MULTI-POLE MAGNETIC CIRCUIT COMPARISONS Permanent magnets can be magnetized with two or more (4, 6, 8, etc.) poles, using permanent or pulse magnetic flux. Pulse magnetization allows achievement of larger magnetic fields necessary for Nd-Fe-B or Sm-Co magnets. Multi-pole magnetization requires special magnetization heads with preformed windings which allow achievement of required distribution of magnetic [...]
Magnet Concept Am area of the magnet, is the cross sectional areal of the magnet perpendicular to the central flux line, measured in sq.cm. at any point along its length. In design, am is usually considered the area at the neutral section of the magnet. B Magnet induction, is the magnetic field induced by a [...]
Magnetic Switchable Device A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics, metalworking, lifting, and robotics, to attach items to metal surfaces [...]
Voice Coil Motor Magnets Voice coil motors are a special form of linear motion motor, and also famous for its working principle which similar to the loudspeaker. Voice coil motor has a simple structure, low volume and noise, in the meanwhile, its specific thrust, acceleration, response speed and accuracy are also excellent. Besides, voice coil [...]
Magnetic losses Reversible losses are normal behavior for all magnetic materials. As the remanence of the all the magnetic materials decreases with increasing temperature, the temperature coefficient is negative, it is to be expected that the magnetic field of a magnet also will decrease with an increase of the temperature. However, this decrease of magnetic [...]
Magnetic Working Point Magnetic Working point (Magnetic operating point) is a point, where the working line (load line) intersects the magnet's B-H demagnetization curve, and indicates the B and H state of the magnet in the magnetic circuit. Knowing the working point is essentia lasit makes possible to forecast the magnetic flux density Bd that [...]

Ceramics vs Alnico for Guitar Pickups When I read that ceramic magnets sound harsh and alnico magnets sound sweet, I ask myself, " Who the hell preaches such nonsense?" There are harsh-sounding pickups with alnico magnets and sweet-sounding pickups with ceramic magnets and vice-versa! A magnet by itself has no sound, and as a part of [...]
