摘要：

We present a simple experiment to measure the magnetic dipole moment of a magnet using two identical magnets and spring dynamometers. The experiment illustrates the concept of a dipole field, as well as the interaction between two magnetic dipoles. The validity of the magnetic dipole approximation. is discussed. The experiment also makes it possible to obtain the remanent magnetization of rare earth magnets. (C) 2006 American Association of Physics Teachers.
