Applications of Diamagnetism

Diamagnetism has various applications, which are:

Magnetic Levitation

Diamagnetic materials can be levitated in a strong, inhomogeneous magnetic field, demonstrating the phenomenon of magnetic levitation. This property has been used in research and demonstration experiments, such as levitating small objects like graphite and live organisms like frogs.

Magnetic Shielding

Diamagnetic materials can be used for magnetic shielding, which involves creating a barrier that redirects magnetic fields away from sensitive equipment or devices. It protects sensitive electronic devices, scientific instruments, and medical equipment from external magnetic interference.

Superconductors

Superconductors exhibit perfect diamagnetism and are used in applications such as magnetic levitation trains (maglev), MRI machines, and energy-efficient power transmission. They expel external magnetic fields from their interior, a property known as the Meissner effect.

Meissner Effect

Meissner Effect is a phenomenon observed in superconductors, where these materials expel all magnetic fields from their interior when cooled below a critical temperature. This results in the magnetic field being bent around the superconductor. Meissner effect is a manifestation of perfect diamagnetism in superconductors, leading to the complete expulsion of magnetic fields from their interiors, a property that is not observed in normal materials.

This effect is a defining characteristic of superconductivity and results from the absence of electrical resistance in superconducting materials, allowing them to maintain persistent screening currents that oppose any applied magnetic field.

Diamagnetism is the property of materials that are repelled by a magnetic field. When an applied magnetic field creates an induced magnetic field in these materials in the opposite direction, it causes a repulsive force.
