Magnetic hand separator for heavy minerals
Magnetic recording media: VHS tapes contain a reel of magnetic tape. The information that makes up the video & sound is encoded on the magnetic coating on the tape. Common audio cassettes also rely on magnetic tape. Similarly, in computers, floppy disks & hard disks record data on a thin magnetic coating.[20]
Credit, debit, & automatic teller machine cards: All of these cards have a magnetic strip on one side. This strip encodes the information to contact an individual’s financial institution & connect with their account(s).[21]
Older types of televisions (non flat screen) & older large computer monitors: TV & computer screens containing a cathode ray tube employ an electro Magnet for sale to guide electrons to the screen.[22]
Speakers & microphones: Most speakers employ a permanent Magnet for sale & a current-carrying coil to convert electric energy (the signal) into mechanical energy (movement that creates the sound). The coil is wrapped around a bobbin attached to the speaker cone & carries the signal as changing current that interacts with the field of the permanent magnet. The voice coil feels a magnetic force & in response, moves the cone & pressurizes the neighboring air, thus generating sound. Dynamic microphones employ the same concept, but in reverse. A microphone has a diaphragm or membrane attached to a coil of wire. The coil rests inside a specially shaped magnet. When sound vibrates the membrane, the coil is vibrated as well. As the coil moves through the magnetic field, a voltage is induced across the coil. This voltage drives a current in the wire that is characteristic of the original sound.
Electric guitars use magnetic pickups to transduce the vibration of guitar strings into electric current that can then be amplified. This is different from the principle behind the speaker & dynamic microphone because the vibrations are sensed directly by the magnet, & a diaphragm is not employed. The Hammond organ used a similar principle, with rotating tonewheels instead of strings.
Electric motors & generators: Some electric motors rely upon a combination of an electro Magnet for sale & a permanent magnet, and, much like loudspeakers, they convert electric energy into mechanical energy. A generator is the reverse: it converts mechanical energy into electric energy by moving a conductor through a magnetic field neodymium gold plated magnets Neodymium magnets appear in products such as microphones, professional loudspeakers, in-ear headphones, guitar and bass guitar pick-ups, and computer hard disks where low mass, small volume, or strong magnetic fields are required. Neodymium
neodymium magnets Neodymium magnets appear in products such as microphones, professional loudspeakers, in-ear headphones, guitar and bass guitar pick-ups, and computer hard disks where low mass, small volume, or strong magnetic fields are required. Neodymium
neodymium ring magnet Neodymium magnets (actually an alloy, Nd2Fe14B) are the strongest permanent magnets known. A neodymium magnet of a few grams can lift a thousand times its own weight. These magnets are cheaper, lighter, and stronger than samarium–cobalt magnets.
neodymium ring magnets Here are some of the magnet manufacturers names you should look for:Always read the reviews of the specific magnet before making a purchase to see how others have rated it.

neodymium sphere magnets Certain transparent materials with a small concentration of neodymium ions can be used in lasers as gain media for infrared wavelengths (1054–1064 nm), e.g. Nd:YAG

small magnets Neodymium glass solid-state lasers are used in extremely high power (terawatt scale), high energy (megajoules) multiple beam systems for inertial confinement fusion. Nd:glass lasers are usually frequency tripled to the third harmonic at 351 nm in laser fusion devices.
sphere magnets Neodymium magnets appear in products such as microphones, professional loudspeakers, in-ear headphones, guitar and bass guitar pick-ups, and computer hard disks where low mass, small volume, or strong magnetic fields are required. Neodymium
super magnet modeling on how density, temperature, and pressure interact inside warheads. HELEN can create plasmas of around 106 K, from which opacity and transmission of radiation are measured..
Medicine: Hospitals use magnetic resonance imaging to spot problems in a patient’s organs without invasive surgery.
Chemistry: Chemists use nuclear magnetic resonance to characterize synthesized compounds.
Chucks are used in the metalworking field to hold objects. Magnets are also used in other types of fastening devices, such as the magnetic base, the magnetic clamp & the refrigerator magnet.
