  This is a report on a dynamic autonomous magnetic interaction which does not
depend on polarities resulting in short ranged repulsion involving one or more
inertial bodies and a new class of bound state based on this interaction. Both
effects are new to the literature, found so far. Experimental results are
generalized and reported qualitatively. Working principles of these effects are
provided within classical mechanics and found consistent with observations and
simulations. The effects are based on the interaction of a rigid and finite
inertial body (an object having mass and moment of inertia) endowed with a
magnetic moment with a cyclic inhomogeneous magnetic field which does not
require to have a local minimum. Such a body having some degrees of freedom
involved in driven harmonic motion by this interaction can experience a net
force in the direction of the weak field regardless of its position and
orientation or can find stable equilibrium with the field itself autonomously.
The former is called polarity free magnetic repulsion and the latter magnetic
bound state. Experiments show that a bound state can be obtained between two
free bodies having magnetic dipole moment. Various schemes of trapping bodies
having magnetic moments by rotating fields are realized as well as rotating
bodies trapped by a static dipole field in presence of gravity. Also, a special
case of bound state called bipolar bound state between free dipole bodies is
investigated.
