Long-Distance Transfer and Routing of Static Magnetic Fields

Long-distance transfer and routing of static magnetic fields.

We show how the static magnetic field of a finite source can be transferred and routed to arbitrary long distances. This is achieved by using transformation optics, which results in a device made of a material with a highly anisotropic magnetic permeability. We show that a simplified version of the device, made by a superconducting-ferromagnet hybrid, also leads to an excellent transfer of the ...

MRI and Static Electric and Magnetic Fields

Safety of strong, static magnetic fields.

Issues associated with the exposure of patients to strong, static magnetic fields during magnetic resonance imaging (MRI) are reviewed and discussed. The history of human exposure to magnetic fields is reviewed, and the contradictory nature of the literature regarding effects on human health is described. In the absence of ferromagnetic foreign bodies, there is no replicated scientific study sh...

Biological Effects of Static Magnetic Fields

Stable Magnetic Fields in Static Stars

We prove that static fluid stars can stably support magnetic fields (within the ideal MHD approximation).
