A Simple Demonstration of a General Rule for the Variation of Magnetic Field with Distance
Kodama, K.
Physics Education, v44 n3 p276-280 May 2009
We describe a simple experiment demonstrating the variation in magnitude of a magnetic field with distance. The method described requires only an ordinary magnetic compass and a permanent magnet. The proposed graphical analysis illustrates a unique method for deducing a general rule of magnetostatics. (Contains 1 table and 6 figures.)
