Abstract

Recently the author reported the feasibility of envisioning a scenario where a massive permanent magnetic dipole bounces off and oscillates about an invisible horizontal magnetic net in the presence of gravity. The scenario has been revisited, modifying its physical contents. The modification embodies analysis of the impact of the induced current due to the falling magnetic dipole. The induced current counteracts the conduction current and alters the dynamics and kinematics of the motion. This rapid communication reports the recent advances.

Summary

Motivations and Goals

In [1] we utilize the well-known recipe for a magnetic field of a looping conduction DC along the symmetry axis perpendicular to the plane of the loop. For the sake of simplicity we assume this change comes about from the variation of the axial component of the magnetic field of the magnetic dipole. R, n and ic are the radius of the loop, number of the turns and the conduction current, respectively This equation is to apply to a cylindrical permanent magnetic dipole of a circular base radius r and a magnetic dipole moment μ. The flux of this field through the area of the circular looping DC is πR2B z.
