A Magnetic field is an invisible flux moving from one end of the magnet to the other. Shown in Figure1. The flux consists of moving or spinning electrically charged particles invisible to the eye. If the max working temperature meet the requirement , permanent magnets can retain the magnetic field for very long time even forever. Magnets have potential energy which means that they have the ability to conserve energy. The magnet will display or release some of its conserved energy when pulling towards or attaching to something then conserve or store the energy that the user exerts when pulling it off.
Every magnet has a north seeking and a south seeking face on opposite ends. The north face of one magnet will always be attracted towards the south face of another magnet.
Discs & Cylinders
Disc and Cylinder magnets can be axially or diametrically magnetized.
Blocks
Block magnets are defined by three dimensions: Length, Width and Thickness. To be consistent, we define the Thickness dimension along the axis of magnetization.
The thickness is usually the smallest dimension, but not always!
We’re sometimes asked if we can provide block magnets magnetized through the length or width. Yes, we do have some long “bar” magnets, where the magnetization is in the longest dimension. We do still define this as the Thickness, though.
Magnetized Through Thickness
Rings
Ring magnets can be axially or diametrically magnetized.
Axially Magnetized
Diametrically Magnetized
Spheres
Spheres can only be axially magnetized. There is only one possible direction.
Disc and Cylinder magnets can be axially or diametrically magnetized.
Axially Magnetized
Arc Segments
Arc Segment magnets can be magnetized in one of four directions.

South on the Outside Face
