MAGNETIC WHEEL
First Claim
1. Magnetic circuit having (a) one or more permanent magnets as a source of magnetic flux, (b) at least two oppositely polarisable pole extension bodies associated with the magnetic flux source, the bodies being disc, wheel, roller or similarly shaped with an outer circumferential surface and held rotatable about respective axes of rotation, and (c) a counter body having ferromagnetic properties which is arranged to cooperate with the rotatable pole extension bodies in providing an external flux path for the magnetic flux when in magnetic contact with the circumferential surface of the pole extension bodies, the magnetic flux source being held stationary relative to the rotatable pole extension bodies.

Abstract
Magnetic circuit that has (a) a source of magnetic flux which includes an electromagnet or one or more permanent magnets, (b) at least two oppositely polarisable pole extension bodies associated with the magnetic flux source, the bodies being disc, wheel, roller or similarly shaped with an outer circumferential surface and held rotatable about respective axes of rotation, and (c) a ferromagnetic counter body which is arranged to cooperate with the pole extension bodies such as to provide an external flux path for the magnetic flux when in magnetic proximity or contact with the circumferential surface of the pole extension bodies, which is characterised in that the magnetic flux source is held stationary relative to the rotatable pole extension bodies.

2. Vehicle capable of magnetically attaching to a magnetically attractive substrate, including a vehicle body at which are supported at least two wheel members and at least one magnet exhibiting a N—
- and a S-pole, wherein the wheel members include magnetically passive but polarisable material, wherein the wheel members and the magnet(s) are spatially located on the vehicle body in a manner wherein the wheel members provide rotatable, oppositely polarisable pole extension elements of the N— and
S-poles of the otherwise stationary magnet(s), whereby resting of the wheel members on the surface of a magnetically attractive substrate creates a closed magnetic circuit encompassing the magnet, pole extension wheel members and the substrate. - View Dependent Claims (4, 6, 7)

3. Support appliance capable of magnetically retaining attached to it in an otherwise displaceable manner a magnetically attractive body, including a support structure at which are mounted at least two wheel or roller members arranged for rotation about respective axes, and at least one magnet exhibiting a N—
- and S-pole mounted at the support body separate from the wheel or roller members, wherein the wheel members include magnetically passive but polarisable material, and wherein the wheel or roller members are spatially located on the support structure in a manner wherein the wheel members provide rotatable, oppositely polarisable pole extension elements of the N— and
S-poles of the otherwise stationary dipole magnet, whereby bringing a magnetically attractive substrate into surface contact with the peripheral surface of the wheel members creates a closed magnetic circuit encompassing the magnet, pole wheel or roller members and the substrate. - View Dependent Claims (5, 8, 9, 10, 11, 12, 13, 14, 15, 16)
