4. Conversion of Mechanical Energy into Another Form of Mechanical Energy

These devices operate using forces created directly between two magnets. These forces are proportional to the square of the magnetic flux generated by the magnet and to the magnet’s surface area:

F=B2S/2μ0

Due to their high magnetic flux density, rare-earth magnets are particularly valuable because they can generate relatively strong magnetic fields. Depending on the orientation of the magnets, two types of phenomena occur between two parts containing magnets, each with numerous applications:

  • repulsion or attraction phenomena used in:

    • ...
