Magnetic propulsion for magnetically levitated trains
Cryogenics, 1973Abstract One of the main problems associated with magnetically levitated trains is the means of propulsion. A system is described whereby the repulsion from the superconducting magnets, in addition to levitating the train, can also be used to propel it.

Physics of magnetic propulsion
Progress in Aerospace Sciences, 2005Abstract The flight of a magnetic vehicle is expected at the expense of the electrodynamic lift and thrust force of interaction with the natural magnetic field and with the eddy currents in ground or water at low altitudes. It would present in future an alternative to rocketry and aviation owing to the expected better efficiency, constant mass and ...

Magnetic Active Matter Based on Helical Propulsion
Accounts of Chemical Research, 2018Micro- and nanomotors are nonliving micro- and nanoparticles that are rendered motile by supplying energy from external sources, for example, through asymmetric chemical reactions or the application of electric, magnetic, optical, or acoustic fields. Their study is interesting for two reasons.

Controlled Propulsion of Artificial Magnetic Nanostructured Propellers
Nano Letters, 2009For biomedical applications, such as targeted drug delivery and microsurgery, it is essential to develop a system of swimmers that can be propelled wirelessly in fluidic environments with good control. Here, we report the construction and operation of chiral colloidal propellers that can be navigated in water with micrometer-level precision using ...

Magnetic propulsion and ultrasound tracking of endovascular devices
Journal of Robotic Surgery, 2011In this paper a robotic means of magnetic navigation of an endovascular device a few millimeters in diameter is presented. The technique, based on traditional computer-assisted surgery adapted to intravascular medical procedures, includes a manipulator for magnetic dragging interfaced with an ultrasound system for tracking the endovascular device.

Electromagnetic Propulsion for Magnetically Levitated Vehicle
MAGNETISM AND MAGNETIC MATERIALS — 1973: Nineteenth Annual Conference, 1974MAGNEPLANE,1,2,3 a magnetically levitated and propelled vehicle, utilizes superconducting coils to interact with the traveling magnetic field of a linearly disposed three phase stator winding. The three phase forces acting on this linear synchronous motor (LSM) are analyzed in terms of harmonic components. The forces are calculated from the gradient of

Propulsion of magnetically levitated trains
Cryogenics, 1976A propulsion system for magnetically levitated trains is proposed. A method of periodically energizing magnetic loops on a train moving over a periodically undulating track allows the net repulsive magnetic force to tilt forward or backward for either propulsion or braking. The principle is explained and a specific example discussed.
