The magnetic field of larger magnets can be obtained by modeling them as a collection of a large number of small magnets called dipoles each having their own m. The magnetic field produced by the magnet then is the net magnetic field of these dipoles; any net force on the magnet is a result of adding up the forces on the individual dipoles.
Get PriceThe SI unit for flux density, or induction, is the tesla (T). This property is also referred to as the B field. In the equations from our Surface Fields article, we use a "B" to denote this term.. Unlike Magnetic Flux above, the Flux Density defines some size for the loop of wire in that example.
Get PriceAm Area of the magnet, is the cross sectional area of the magnet perpendicular to the central flux line, measured in sq. cm. at any point along its length. In magnet design, Am is usually considered the area at the neutral section of the magnet. B Magnetic induction, is the magnetic field induced by a field strength, H, at a given point. It is ...

Get PriceMagnets. Magnets attract certain metals. They have two poles that attract or repel the poles of other magnets. Lines of force form a powerful magnetic field around a magnet. Magnets come in many shapes and sizes, and are used for many purposes. Without magnets, our lives would be quite different.
Get PriceThe concept of the unit magnet pole is useful for analytical exploration of the magnetic field since it brings out in a quantitative manner the fact that the magnetic field is a field of force and is comparable in some respects, although not entirely, to the electric field.
Get PricePrecision Torque’s permanent magnet clutches and brakes have a torque rating up to 300 lbin. These units operate with two fixed magnets that react with a rotating third magnet to produce SMOOTH torque. The torque level is adjusted by changing polar relationships of fixed magnets.
Get PriceSep 22, 2019· Magnets come in many strengths, and you can use a gauss meter to determine the strength of a magnet. You can measure the magnetic field in teslas or the magnetic flux in webers or Teslas • m 2 ("tesla square meters"). The magnetic field is the tendency for a magnetic force to be induced on moving charged particles in the presence of these magnetic fields.
