A good magnetic rods should do uniform spatial distribution of magnetic flux lines, the maximum magnetic flux density distribution point as magnetic rods filled the entire root, because the general production is on the move
Commodities transmission lines, magnetic stick surfaces should be smooth resistance, does not contain environmentally harmful substances, to avoid contaminated material and the environment.
Magnetic rods work environment determines that it must have a certain degree of corrosion resistance, high temperature resistance, and some situations require a relatively strong magnetic induction. By using
Magnetic sheets of different drum separator thickness can be different magnetic induction. Select a different magnetic bar magnets can determine the maximum magnetic flux density and temperature resistance, generally succeed in regular
Regulations ∮ 25 magnetic rods to achieve more than 10,000 gauss magnetic induction surface models that require high performance NdFeB magnets, high temperature magnetic bar at a temperature of over 150 degrees
These generally choose cube magnets SmCo magnet, but do not choose large diameter SmCo magnetic rods, after samarium cobalt price is very high and a magnetic wand price reaches tens of thousands of yuan,

History
Sturgeon (Sturgeon) electromagnet. AD 1825, Englishman William Sturgeon (William Sturgeon, 1783 年 -1850 years) will pass a current of insulated wire wound rod, invented the electromagnet.
American physicist Joseph Henry Drawer magnets (Joseph Henry 1797 年 -1878 years) after learning the news, the soft iron core coil winding intensive, the use of current small battery powered, will be able to pick up a ton of iron.
Manufacture
Simple homemade electromagnet:
Need wire, nails to make its body; battery or power supply supplied with current.
Note:
To scrape the end enameled paint, or fire.
To enameled wire wound in the same direction.
To the end of enameled knot tied.
Feature
Both ends of the electromagnet and the permanent magnet strongest magnetic force.
Electromagnet magnetic force can be changed.
The direction of the electromagnet can be changed.
Solenoid magnet can control freely.
1822, French physicist Arago and Gay-Lussac found that when the current through the winding which has iron, it can make the iron wire magnetized. This is actually the original discovery of the principle electromagnet. 1823, Sturgeon also did a similar experiment: He is not in a U-shaped iron bar magnet stick around for 18 laps on the bare copper, when copper and voltaic cell is turned on, around the U type iron bar on the copper coils that produce a dense magnetic field, thus making U-shaped iron bar into a "magnet." This magnetic energy than the permanent magnet on the big release times can be, it can pick up more than 20 times its weight of iron, and drum separator when the power is cut off, U-shaped iron rods on what it could not suck again become an ordinary iron bar. Sturgeon electromagnet invented to make people see the magnetic energy to electrical energy into the bright future of this invention soon in the United Kingdom, the United States and some Western European coastal countries spread. 1829, U.S. scientist Henry Sturgeon electricity electromagnet device made some innovations, insulated wire instead of bare copper wire, copper wire so do not worry about being too close to the short circuit. As the wire with the insulation layer, they can be wound together tightly around the enclosure, the more intensive the coil, the stronger the magnetic field generated, thus greatly improving the ability of electrical energy into magnetic energy. To 1831, Henry trial out an update electromagnet, although its volume is not large, but it can pick up the one-ton iron. The invention also enables the electromagnet generator power has been greatly improved.

the electromagnet for what purposes
Switch (relay), cranes, bells, telephones, including stereo speakers
Solenoid has many advantages: it can be energized without magnetic, power to control the strength of its magnetic strength can be controlled by a current, its polar direction of the current can be controlled by the conversion, it is very easy to use . Therefore, in production, life, science and technology many uses. For example, there is a large crane electromagnetic solenoid, pass on the current, one will be able to put a few tons of steel material handling sucked up to the specified location. drum separator The grinding machine shop work bench without clamps, and was very firmly workpiece being sucked out in the above process. Workbench is a large electromagnet, the power attracted to the magnetic steel or the workpiece there, when not energized is not magnetic, steel or workpiece which may release, by the electromagnet electromagnetic effects processing machine iron and non-ferrous materials can be separated .
