Superconductive materials, those that feature no resistance to electricity, display a pronounced form of diamagnetism
below a critical temperature, at which point they begin completely repelling magnetic fields.
A] indicates that the tube and sample have a net diamagnetism
Based on the diamagnetism
of the superconductor, people have designed various magnetic lenses composed of superconductors to concentrate the DC magnetic field when applying a background magnetic field to the lenses [6-10].
He discovered the phenomenon of diamagnetism
, in which substances were repelled by a magnetic field, and thus aligned themselves at right angles to it; the same year saw his discovery of the effect in which magnetism rotates the plane of polarization of a ray of light, and his first success in illuminating a line of force.
causes lines of magnetic flux to curve away from the material and creates a magnetic field in opposition to the externally applied magnetic field, a repulsive effect.
However, most biological materials are affected by a different type of magnetism called diamagnetism
, in which objects are weakly repelled from magnetic fields.
