Web3. Measure the axial field distribution of a circular coil. Determine graphically and arithmetically the distance from the coil center, at which the maximum value of the magnetic flux density is decreased to one half. 4. Measure the axial field distributions of a pair of circular coils for three different distances between the coils. WebIn 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. For the current loop, this limit is most easily derived from the vector potential: = =,where μ 0 is the vacuum permeability constant and 4π r 2 is the surface of …
