Run a Current

Steve : Or you could just run a current through all electrical conductor &  produce a magnetic field that way.

This article is about objects &  devices that produce magnetic fields. For a description of magnetic materials, see Magnetism. For other uses, see   Magnet for sale  (disambiguation).

A “horseshoe magnet” made of alnico, an iron alloy. The magnet, made in the shape of a horseshoe, has the two magnetic poles close together. This shape creates a strong magnetic field between the poles, allowing the   Magnet for sale  to pick up a heavy piece of iron.

A   Magnet for sale  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.is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, &  attracts or repels other magnets. A permanent   Magnet for sale  is an object made from a material that is magnetized &  creates its own persistent magnetic field. An everyday example is a refrigerator   Magnet for sale  used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel &  cobalt &  their alloys, some alloys of rare-earth metals, &  some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a   Magnet for sale  strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.
