Question

hlo guyz...explain what is magnetic field density , magnitizing force... strength of magnetic field...magnetic induction and formula B=uH ...little confused in all the above ..i mean clear btana plz ...ye kuch to 1 hi same ..h but plz btado .m inme bdi confusion h...​

Answer 1

Answer:

magnetic field density:-

In SI units, B is measured in teslas (symbol: T) and correspondingly ΦB (magnetic flux) is measured in webers (symbol: Wb) so that a flux density of 1 Wb/m2 is 1 tesla. The SI unit of tesla is equivalent to (newton. second)/(coulomb. metre).

magnitizing force:-

magnetic intensity applied to points within a magnetizable substance. — called also magnetic force.

Answer 2

Answer:

magnetic field is a vector field that describes the magnetic influence on an electric charge of other moving charges[1][2] or magnetized materials. A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.[1][3] The effects of magnetic fields are commonly seen in permanent magnets, which pull on magnetic materials such as iron, and attract or repel other magnets, creating a torque. In addition, a magnetic field that varies with location will exert a force on a range of non-magnetic materials by affecting the motion of their outer atomic electrons. Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, they are described as a map assigning a vector to each point of space or, more precisely—because of the way the magnetic field transforms under mirror reflection—as a field of pseudovectors.

In electromagnetics, the term "magnetic field" is used for two distinct but closely related vector fields denoted by the symbols B and H. In the International System of Units, H, magnetic field strength, is measured in the SI base units of ampere per meter (A/m).[4] B, magnetic flux density, is measured in tesla (in SI base units: kilogram per second2 per ampere),[5] which is equivalent to newton per meter per ampere. H and B differ in how they account for magnetization. In a vacuum,the two fields are related through the vacuum permeability, {\displaystyle \mathbf {B} /\mu _{0}=\mathbf {H} }{\displaystyle \mathbf {B} /\mu _{0}=\mathbf {H} }; but in a magnetized material, the terms differ by the material's magnetization at each point.
