Magnetic Moment Formula Class 12 Physics ~ Indeed lately is being sought by users around us, perhaps one of you. Individuals now are accustomed to using the internet in gadgets to view image and video data for inspiration, and according to the title of the article I will discuss about Magnetic Moment Formula Class 12 Physics. ψ r m. τ m b. Magnetic moments can be demonstrated by a lot of things such as a loop of electric current an electron a bar magnet a molecule or a planet. When a magnet of length i pole strength m and of magnetic moment m is turned into a semicircular arc then it new magnetic moment m m 2r m 2 1 π πr i 2m π m m l. R 4 π r 3. Magnetic field magnitude frac permeability of free space current magnitude 2 pi distance. It is a vector quantity and its direction is from south pole to north pole. Where m is pole strength and 21 is dipole length directed from the si unit of magnetic dipole moment is a m 2 or j t. B is the external magnetic field. Magnetic dipole moment the magnetic field b due to a current loop carrying a current i of radius r at a distance l along its axis is given by. M 1 2 v r j d v. Where m is pole strength and 2i is dipole length directed from s to n. Besides the unit of a magnetic field is tesla t. M is the magnetic moment. Here r is the position vector j is the electric current density the integral is a volume integral. B frac μ 0 i r 2 2 r 2 l 2 frac32. This is mathematically represented as. The magnetic moment of a magnet can be defined as the quantity that finds the force a magnet is able to exert on electric currents and the torque that the magnetic field will exert on it. Si unit of magnetic field is wm 2 or tesla and cgs unit of magnetic field is gauss or oersted 1 gauss 10 4 tesla. The magnetic dipole moment of a magnetic dipole is given by.
This is known as permeability of free space and has a value mu 0 4 pi times 10 7 t cdot m a. Si unit of magnetic field is wm 2 or tesla and cgs unit of magnetic field is gauss or oersted 1 gauss 10 4 tesla. Magnetism and matter class 12 notes chapter 5.
