The magnetic field generated by any magnet is always strongest at either pole. 9 UnnaturalMagnetic anisotropy means that the magnetic properties depend on the direction in which they are measured. The poles are regions where the magnet is strongest. Diamagnets repel, and are repelled by a strong magnetic field. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. Ferromagnetic materials can be influenced by translational (linear) and torque (rotational) forces exerted by the static magnetic field of the magnetic resonance imaging (MRI) scanner. There are various kinds of magnetism, out of which ferromagnetism is the strongest type. The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. If you want to generate the largest magnetic field with the lowest electrical power for a given core material and conductor material: Build a closed ring out of the magnet material e.
