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 [...]

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 [...]

Anti-shoplifting Devices Electromagnets

Anti-shoplifting Devices Electromagnets Anti-shoplifting Devices Each year, businesses lose billions to shoplifting. To prevent this, most stores have invested in security. Common systems include electronic surveilance, security personel, and alarm systems. One of these systems, called the EM system, uses electromagnets to thwart shoplifters. Electromagnetic (EM) System The EM system, dominant in Europe, uses electromagnetic [...]

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 [...]

Electromagnets

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.

The Magnetic Poles And Their Significance

The Magnetic Poles And Their Significance Magnets An object that has the ability to generate a magnetic field is known as Magnet. A magnet has the ability to attract ferrous objects like iron, steel, nickel and cobalt. In the early days, around 600 B.C. the Greeks observed that the naturally occurring ‘lodestone’ attracted iron pieces [...]

Understanding the Milky Way’s Magnetic Field

Understanding the Milky Way's Magnetic Field - You probably already know that our planet has an intrinsic magnetic field, and you might even know that it’s caused by the earth’s swirling molten core. What you might not know, however, is that plenty of other cosmic objects in the universe have magnetic fields, including our very [...]

Neodymium Magnet

Neodymium Magnet Description The tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA~7 teslas - magnetic field strength H in A/m versus magnetic moment in A.m2). This gives the compound the potential to have high coercivity (i.e., resistance to being demagnetized). The compound also has a high saturation magnetization (Js ~1.6 T or [...]
