http://www.phys.ufl.edu/~acosta/phy2061/lectures/MagneticDipoles.pdf WebA tiny current loop act's as a tiny magnet technically called a magnetic dipole. The strength of that tiny magnet, the magnetic dipole moment m, is given by m = NIA, giving the units - Ampere meter square. The magnetic dipole moment is a vector quantity and its direction is given by the right-hand thumb rule. Magnetic dipoles are different than ...

Web7 sep. 2011 · In order to find the magnetic moment of the current loop, you will need to multiply the current by the area enclosed by the current. Since the current runs around the edge of the "slice" of the sphere, you need the area of the slice, designated in the picture. Note that the radius of this circle is not , the radius of the sphere. http://kirkmcd.princeton.edu/examples/rotatingshell.pdf WebThe ring represents the current loop, which goes into the page at the x and comes out at the dot. In classical physics, the magnetic field of a dipole is calculated as the limit of either a current loop or a pair of charges as the source shrinks to a point while keeping the magnetic moment m constant. herre ytterjakke
