Magnaprobe: visualizing the invisible- a small bar magnet on a gimbal mount demonstrates magnetic field direction for points in space around a magnetized object. Red indicates the north pole and blue the south pole of the Magnaprobe dipole- the red end is attracted to any other magnet’s south pole like a 3D compass. Magnetic viewing film reveals a cross section of the magnetic field where colors correspond to intensity, but can’t show the direction of the field like the magnaprobe device can. To
