Hard Ferrite Magnet The hard ferrite is manufactured with SrO or BaO and Fe2O3 by ceramic process. Because of its cheaper price, and production process is relatively simple, compared with the prices of their products relatively cheap in terms of other magnets. The main raw materials of ferrite magnets is oxide, so, it could not [...]
Things to Do With Rare Earth Magnets Neodymium iron boron (NIB) magnets are usually called neodymium or rare-earth magnets. They are extremely strong, having a magnetic pull-force that is 10 times greater than ferrite magnets and 20,000 times greater than the Earth's magnetic field. These magnets are brittle as well as powerful and they can [...]
How to Demagnetize a Magnet Permanent magnets require special manufacturing techniques in a magnetic field to get the metal to stay in the proper alignment. In order to demagnetize a magnet, you need to change this alignment. This process usually requires a high amount of heat, or a strong magnetic field at a reverse polarity [...]
Flexible Magnetic Tape Material Magnetic tape is made from strontium ferrite magnet material, bonded into a thermo-plastic which is then extruded as a strip. Use with steel tape for secondary glazing or for signs and labels. The steel tape has an adhesive back and can be permanently fixed to a surface to allow magnets, magnetic [...]

Magnetic Swarf Wand NEW PRODUCT Separate small parts after rumbling Quick release handle Permanent magnet - never needs re-magnetising Lightweight, non-rusting shaft Holding capacity: 6.35kg Quickly and safely pick-up iron and [...]
Daily Life Electromagnets Electromagnets are common in everyday appliances, and are becoming more common as the need for technology increases. Electromagnets are found in doorbells, hard drives, speakers, MagLev trains, anti-shoplifting systems, MRI machines, microphones, home security systems, VCRs, tape decks, motors, and many other everyday objects. How An Electromagnet Works A basic electromagnet consists [...]
Permanent electromagnets have a permanent magnetic field, but when supplied with power, the magnetic field is neutralized. This type of electromagnets is used when the magnetic field is required to work permanent electromagnets(magnetic field on) most of the time, and neutralized once in a while (for example a door lock). If the magnetic field should [...]
Hard Drives Electromagnets Hard Drives Although we may not see them every day, hard drives do immensely important behind-the-scenes work. Hard drives store government files, weather reports, your emails, the pictures on your digital camera, and many other things. In fact, hard drives are the backbone of the Internet: almost everything you see online is [...]
Doorbells Electromagnets Doorbells Although almost every house has a doorbell, we rarely stop and think about how they work. At the basic level, a doorbell consists of an electromagnet that triggers some kind of noise (a buzzer, bell, or chime). When you press the button of a doorbell, you are completing the bell's circuit, activating [...]
Maglev Train Electromagnets Maglev trains (short for magnetic levitation trains) are modern trains that leverage electromagnets. These trains are faster, quieter, smoother, and more efficient than their wheeled counterparts. Maglev trains are common in many Asian and European countries, and are becoming popular in airports as well. Today's fastest Maglev train can speed along at [...]
