How to Increase the Strength of an Electromagnet Electromagnets work just as well as permanent magnets. In fact, they are even more useful, because you can turn them on and off. You'll find electromagnets in hard drives, speakers and even in sophisticated equipment like MRI machines. You obviously need a stronger electromagnet for a particle [...]
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 [...]
Round and Rectangular Electromagnets Round and Rectangular Flat-Faced Electromagnets are available in a variety of sizes. Flat-Faced magnets should only be used on flat, smooth material where the entire magnet face is in contact. They can be used in manually operated or automated applications. Magnets listed utilize 12 volt D.C. current (24VDC and 110VDC are [...]
Explanation of the Solenoids Device Types Acting Solenoids Depending on the type of motion cycle, a distinction is made between single, double and reverse acting solenoids. Single acting solenoids are electromagnets in which the movement from the initial position to the end position is effected by electromagnetic force. An external force is required in order [...]
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. [...]
What Are The Most Common Materials For Magnetic Cores? As we know, the inductor core materials there are many the main iron core, silicon steel sheet core, FeSiAlF core, Mn Zn ferrite core, Ni Zn ferrite magnetic core core. Among them, Mn Zn ferrite core, Ni Zn ferrite magnetic core are ferrite cores. Do you [...]
Brief Introduction Of Ferrite Core Ferrite core is mainly composed of iron (Fe), manganese (Mn), and zinc (Zn) three metal elements, commonly known as manganese-zinc ferrite. Because the annular ferrite core has no air gap and the cross section area is uniform, the magnetic effect is very high. Ferrite rings have a wide range of [...]
Commonly Used Soft Magnetic Core Iron Powder Core Permalloy Powder Core Iron-Silicon-Aluminium Powder Core Magnetic powder core is a kind of soft magnetic material made by mixing and pressing ferromagnetic powder and insulating medium. Ferromagnetic particles are very small (0.5-5 micron used at high frequencies) and are separated by non-magnetic insulating film materials. Therefore, on [...]
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 [...]
Magnetic Jewelry an Overlooked Danger The federal government brands magnets in toys a deadly hazard to children because the tiny, powerful objects can fall out and cause serious, even fatal, internal injuries when swallowed. Yet the Consumer Product Safety Commission has not taken steps to regulate even more powerful magnets when they are sold in [...]
Magnetism as an Energy Source: Understanding Magnetic Force This article will discuss magnetic fields and electromagnetism. An invisible force occurs between two magnets when they are brought close to each other. This force may be an attraction force that pulls the magnets together or a repulsion force that pushes them apart. See Figure 1. Magnetic [...]
