Magnadur is a sintered barium ferrite, specifically BaFe 12 O 19 in an anisotropic form. [1] It is used for making permanent magnets.The material was invented by Mullard and was used initially particularly for focussing rings on cathode-ray tubes.
Ferrite magnets are known for their high magnetic permeability and low electrical conductivity, making them suitable for high-frequency applications. [38] In electric power steering systems, they provide the necessary magnetic field for efficient motor operation, contributing to the system's overall performance and reliability. [39]

Quadrupole magnets are useful as they create a magnetic field whose magnitude grows rapidly with the radial distance from its longitudinal axis. This is used in particle beam focusing. The simplest magnetic quadrupole is two identical bar magnets parallel to each other such that the north pole of one is next to the south of the other and vice ...
