Magnetic Moment Formula Class 12 Physics ~ Indeed recently is being hunted by users around us, maybe one of you personally. People are now accustomed to using the net in gadgets to view video and image data for inspiration, and according to the title of this post I will discuss about Magnetic Moment Formula Class 12 Physics. It is a vector quantity and its direction is from south pole to north pole. Here r is the position vector j is the electric current density the integral is a volume integral. It is a vector quantity and its direction is from south pole to north pole. Give the direction and magnitude of the magnetic field produced by the magnet at a distance of 10 cm from the centre of the magnet on a the axis b the equatorial lines normal bisector of the magnet. The magnetic moment is a vector relating torque of an object to the magnetic field. Db μ o 4 π idl r r 3. This is known as permeability of free space and has a value mu 0 4 pi times 10 7 t cdot m a. A short bar magnet has a magnetic moment of 0 48 j t 1. Where θ is the angle between the direction of the current and μ o is absolute permeability of the free space. M m 2i. 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. Or db μ o 4 π idl sin θ r 2.
