Why don't we use the magnetic field provided by the earth to generate electricity? It sounds like a good idea, but it's not very practical. Before we explain why, let's understand how we generate electricity, in case anyone reading this doesn't already know. Electricity (we say "current") is created when charged particles flow, like water [...]
Scientists design new magnets to provide room for sustained nuclear fusion reactions Scientists are working to realize the potential of nuclear fusion as a nearly inexhaustible source of clean energy, one of the ways that is through new and improved magnets that confine the fields of plasmas so that key reactions can occur . A [...]
Magnets Generate More Electricity in Generators Purdue University researchers have developed a parallel arrangement of inner magnets to reduce size and increase the efficiency of low- to medium-power generators. Source: Purdue University Generators have many uses, from cars to airplanes to microgrids. There is currently a strong desire to reduce size and increase efficiency of [...]
Separator Magnets MPCO engineers and manufactures magnetic pulleys, drums, suspended magnetic separators, and eddy-current separators designed for beneficiation, tramp iron removal, non-ferrous metal recovery and various other separation processing applications. MPCO offers permanent and electromagnetic designs with the option of self-cleaning or manual-cleaning features. Complete systems can be designed into new separation facilities or incorporated [...]
Types of Weak Magnetic Separators The industrial magnetic separation machine can be divided into the weak magnetic separator and strong magnetic separator (high-intensity magnetic separator). This article mainly introduces the types of weak magnetic separators, includes dry type, wet type, and auxiliary equipment. Dry type weak magnetic separators The dry magnetic separator requires the sorted [...]
Electromagnetic Induction Voltage applied to a conductor creates a magnetic field around that conductor. It is possible to reverse this process and for a magnetic field to generate a voltage in a conductor. For this to occur, there must be some relative motion between the conductor and the magnetic field. Electromagnetic induction takes place whenever [...]
Electromagnetic Clutch Types MIC Electromagnetic Clutch Torque Range: 0.226 to 0.79 Nm / 2 to 7 in-lbs. Small clutches for use in copy machines, printers, and other peripheral devices. This one-piece assembly features a custom-molded gear or timing pulley designed to your specifications. Most clutches use a permanent magnet to disengage the armature when it [...]
Electromagnetic Clutches Advantages of use: » Electrically remotely actuated. » Reduced power consumption from engine. » Extended pump life. » Lower operator cost. » Simple installation. » Operator convenience/safety. » Cold weather starting. General description of electromagnetic clutches These are flange mounted, normally a two piece construction clutch typically mounted directly on to the pump. [...]
Electromagnetism & Magnetism Applications Magnetism and moving electrons are closely related to each other. The three phenomena pertaining to electromagnetism are: Moving electric charges produce magnetic fields. Magnetic fields exert forces on moving electric charges. Changing magnetic fields in the presence of electric charges cause electrons to flow In 1820, Danish physicist Hans Oersted noted [...]
Fermilab achieves world-record field strength for accelerator magnet To build the next generation of powerful proton accelerators, scientists need the strongest magnets possible to steer particles close to the speed of light around a ring. For a given ring size, the higher the beam's energy, the stronger the accelerator's magnets need to be to keep [...]
Over-belt Electromagnetic Separator The type over-belt electromagnetic separator is intended for removal of tramp iron from bulk materials transported on conveyor belts or vibratory feeders. The electromagnetic separator is used to protect of process machines against damage caused by an unwanted piece of ferrous metal and also to recover valuable ferrous scrap from waste materials. [...]
What is Speaker Magnet The neodymium speaker magnet produces a magnetic field, and the speaker’s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that [...]
