A permanent magnet for an MRI scanner is made by removing extraneous elements from an ore containing rare earth elements to leave elements Pr and Nd therein, and then selectively stripping therefrom a portion of the element Nd as a byproduct to leave an ore residuum including both elements Pr and Nd therein. The residuum is alloyed with a transition metal to form an alloy therewith. The alloy is then formed into a rare earth permanent magnet configured for use in the MRI scanner.

Permanent magnets, devices including permanent magnets and methods for manufacture are described with the permanent magnet comprising, for example: iron-boron-rare earth alloy particulate having an intrinsic coercive force of at least about 1591 kiloamperes/meter (about 20 kiloOersteds) and a residual magnetization of at least about 0. 8 tesla (about 8 kiloGauss), wherein the rare earth content comprises praseodymium, a light rare earth element selected from the group consisting of cerium, lanthanum, yttrium and mixtures thereof, and balance neodymium; and a binder bonding the particulate.

A FeâBâR type permanent magnetic, consisting of: 13-19 atomic % R, where R consists essentially of a mixture of rare earth elements Nd and/or Pr, and Ce, where Ce is between 0. 2 and 5. 0 wt. % of R; 4-20 atomic % B, and the balance comprising Fe. In a preferred aspect, R comprises 15-16 atomic % B; of which Ce is approximately 0. 5% and the remaining rare earths Pr and Nd are in a ratio of 3:1. A process of producing a FeâBâR permanent magnet as described above, and a FeâBâR magnetic material made by such process.

A method of making a permanent magnet body is provided. The method includes providing a first precursor body comprising a plurality of blocks and magnetizing the first precursor body to form a first permanent magnet body. A recoil magnetization pulse may be applied to the permanent magnet body after the magnetization. The precursor body may be heated during magnetization. A power supply containing a battery may be used to energize a pulsed magnet used to magnetize the precursor body.
