A bar magnet is called a dipole because it has two poles commonly labeled north and south breaking a magnet in two does not produce two isolated poles; each fragment still has two poles similarly two magnets together still exhibit only two poles since to our knowledge there are no magnetic monopoles the dipole is the simplest possible magnetic field.
A bar magnet is called a dipole because it has two poles (commonly labeled north and south).Breaking a magnet in two does not produce two isolated poles; each fragment still has two poles.Similarly, two magnets together still exhibit only two poles.Since, to our knowledge, there are no magnetic monopoles, the dipole is the simplest possible magnetic field source.
A magnetic pull test can be used in comparing two magnetic devices that look very similar on the outside, but may have different magnetic circuitry or magnet material on the inside, resulting in a more, or less, effective magnet.Magnetic pull strength testing can be performed on magnets with round or flat surfaces and on either permanent or .
A permanent magnet has shape of a thin disc with magnetic moment along its axis the radius of the disc is 1 cm.The magnetic field due to it can be assumed to be that due to a molecular current I flowing along the rim of the disc.It B ˉ at a distance of 10 cm from its centre on the axis is 30 μ T, find I (approximately).
Basically, there are two systems of units based on the metric system that is used: the SI unit and CGS units.Thus, we will look at the unit of magnetic field below.Generally, the magnetic field can be defined in several specific ways in relation to the effect it has on the environment.
For a magnet to operate at its BHmax it must have a particular geometry.This geometry is a commonly used ratio in magnetic design and it is the ratio of the Magnetic Length to the Diameter of the Magnet, L/D.
In physics, the energy of a magnet is familiar, that is, it is the energy that is in a magnet.In order for a magnetic field to be generated, one must first work.The energy in a magnetic field is the energy required to align the elementary magnets of a material in parallel.Energy is, therefore, a work, which is required for the rotation of .
Magnet - A magnet is an object made of certain materials which create a magnetic field.Every magnet has at least one north pole and one south pole.By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet.This is an example of a magnetic dipole ( di means two, thus two poles).

The magnetic intensity at a point is defined as the force that unit north – Pole experiences when it is placed in that field.
Magnetic Mic is a universally-compatible mic clip for police and CB radios.It uses a super strong magnet to make hanging your mic faster, easier and safer.It's the microphone holder that lets first responders stay focused on what matters.
Magnetic moment per unit volume.The designation “emu” is not a unit.Recognized under SI, even though based on the defition B = μ o H + J.μ r = μ/μ o = 1 + χ, all in SI.BּH and μ o MּH have SI units J/m 3; MּH and BּH/4π have Gaussian units erg/cm 3.

Magnetic Units of Measurement If the burden of two systems of measurement for common quantities (English vs.Metric) throws your mind into confusion, this is not the place for you! Due to an early lack of standardization in the science of magnetism, we have been plagued with no less than three complete systems of measurement for magnetic .

Neodymium magnets will lose about 1% of their magnetic strength every 10 years due to self demagnetization.BHMax (MGOe) - Maximum Energy Product Measured in Mega Gauss Oersteds This is a direct measurement of a materials maximum magnetic strength after the magnet is fully saturated charged by an external magnetic field.
We can define the magnetic field in many ways corresponding to the effect it has on our surroundings or environment as a result of which, we have the B-field and the H-field (magnetic field denoted by symbol B or H).B-field is a kind of magnetic field, which refers to the force it exerts on a moving charged particle .
The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as 1750.If, for example, the separation between the two poles is doubled, the magnetic force diminishes to one-fourth its former value.Breaking a magnet in two does not isolate its north pole from its south pole.
The 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.
The SI unit for magnetic flux is the weber (Wb).If this flux changes by 1 Wb over a time of 1s, then a voltage of 1 V is induced in a conductive loop encircling it: 1 Wb = 1 Vs.The flux density is called induction.The SI magnetic induction unit B is tesla (T): 1 T = 1 Wb/m 2 = 1 Vs/m 2.Mathematically, magnetic field with density of 1 T .
Where, τ is the torque acting on the dipole; m is the magnetic moment; B is the external magnetic field; Magnetic Moment Unit: In the definition for the current loop, the Magnetic moment is the product of the current flowing and the area, M = I A So the unit conferring to this definition is articulated by Amp-m 2.It can also be suggested in terms of torque and moment.
