Magnetic Field of a Dipole and the Dipole-Dipole Interaction
Kraftmakher, Yaakov
European Journal of Physics, v28 n3 p409-414 May 2007
With a data-acquisition system and sensors commercially available, it is easy to determine magnetic fields produced by permanent magnets and to study the dipole-dipole interaction for different separations and angular positions of the magnets. For sufficiently large distances, the results confirm the 1/R[superscript 3] law for the magnetic field and the 1/R[superscript 4] law for the interaction force between two dipoles, as well as their angular dependences. (Contains 6 figures.)
