  In this paper, we describe a simple apparatus consisting of a scale, capable
of a one milligram resolution, and a commonly obtainable magnet to measure
magnetic forces. This simple apparatus is capable of measuring magnetic
properties of materials in either a research or an instructional laboratory. We
illustrate the capability of this apparatus by the measurement of the force of
iron samples exerted on the magnet, the force of a paramagnetic sample, that by
a current carrying wire, and the force of a high temperature superconductor.
