Magnets exert attractive or repulsive force. This is called magnetism. The magnetic effect is higher in regions closer to the magnetic poles and reduces as one move farther away from the magnetic. The region in which magnetic force is exerted is called a magnetic field.
Magnetic fields can be represented using vectors. This is because these fields have a magnitude and direction.Magnetic Field 1Magnetic Field 1Types of Magnetic flux density BThere are two types of vectors that represent magnetic fields,One is magnetic induction also called as magnetic flux density represented by B and the other is magnetic field strength represented by H.in vacuum, B and H cannot be distinguished.
The magnetic flux density in the B field depends on macroscopic and microscopic current based on the electron movement in the nuclei. Therefore magnetic flux density can be defined in several ways based on the effect of flux density on the environment.Consider a charged particle p moving in a magnetic field with a velocity equal to v. this charge experience a force in the magnetic field. Thisforce can be represented asF = pv *BHere p is the charge of the particlev is the velocity and B is the magnetic field.magnetic flux density can also be defined as equivalent to the torque on a magnetic dipole placed in a magnetic field.
The magnetic flux density is representedusing teslas in SI units andUsing gauss in cgs units. (1 tesla = 10,000 gauss).The SI unit of tesla = (newton × second)/ (coulomb × meter)Magnetic flux density can be measured using magnetometers.The other names for magnetic flux density as used in different industries ismagnetic flux density used by electrical engineers, magnetic induction used by applied mathematicians and electronics engineers and magnetic field used by physicists.Conclusion for
Magnetic flux density BMagnetic flux density depends on macroscopic as well as microscopic current created by electron movement in the nucleus. Magnetic flux density is the term used for magnetic field in B field and opposed to magnetic field in H field that is called magnetic field strength.
