Things to Do With Rare Earth Magnets

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

How to Demagnetize a Magnet

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

Flexible Magnetic Tape

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 [...]

  • Daily Life Electromagnets

Daily Life Electromagnets

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

Permanent electromagnets

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 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 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 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 [...]

  • electromagnet


electromagnets - When an electric current flows in a wire, it creates a magnetic field around the wire. This effect can be used to make an electromagnet. A simple electromagnet comprises a length of wire turned into a coil and connected to a battery or power supply.
