Abstract
An adjustable field magnet assembly comprising at least two magnets rotatably mounted so that the rotation of at least one of the at least two rotatably mounted magnets changes the magnetic field projected by magnet assembly. The magnet is particularly useful in providing a magnet field of variable direction for use in magnetically navigating medical objects in the body by rotating the magnets comprising the assembly and/or rotating the entire assembly.
