  • Another type of device has the two halves of the magnetic array assembled to form a central longitudinally extending bore through which fluid can be flowed and magnetically treated. All fluid traversing the field will be conditioned magnetically.
  • the advantage of using these RPGs in a moving fluid environment is that the fluid passing through the RFG is highly magnetically conditioned because of the magneto hydrodynamic efficiency of the devices.
