Defining The Shape Of Science & Technology


Parallel Path Magnetic Technology

The Basics:


If a permanent magnet were placed in a magnetic circuit as shown all of the flux from the permanent magnet would flow through the upper flux path to the armature and from the armature to the lower flux path and then return to the permanent magnet. 

A magnetic force of attraction exists between the upper & lower flux paths and the armature. For this discussion we assign the amount of this force as 1 unit. 


If another magnet with equal properties is added in parallel to the circuit as shown below the flux through the armature doubles.

By doubling the flux in the magnetic circuit the force of attraction on the armature is now 4 units. 


This is defined by the formula for the magnetic force of attraction. The formula is:

Where F is the force and B is the flux in the air gap and A is the area of a pole face in the air gap and 2Uo is the magnetic constant. Since the only difference between the first and second magnetic circuits is the addition of a second magnet then we can see that the force of attraction can be defined as a function of  B squared. For those knowledgeable about magnet circuits, this is elementary,  but is fundamental to understanding Parallel Path Magnetic Technology. 


If the magnetic circuit is again modified by the addition of a second armature as shown below, each of the permanent magnets now have separate flux paths through their respective armatures. 


It should now be obvious from the above discussion that the resulting force would be 1 unit acting on each armature. Now armed with this basic magnetic theory we are ready to discover what Parallel Path Magnetic Technology is and how it works.
