Özet:

 


 
                         This paper deals with the investigation of braking forces 
induced by eddy currents, which have effects on the permanent magnet moving 
at a constant speed in the direction of the conductive tube axis. The 
analysis is based on calculation of an action of a force between the current 
density, representing the magnet, and the eddy currents. The chosen solution 
is based on classical electrodynamics and can serve as a guide for the 
calculation of other cases, where braking forces are created between the 
moving cell, which is a source of the magnetic field, and a close conductive 
subject. The obtained results indicate the braking force affecting the 
magnet and the dependence of this force on the current. The graphical 
representation of the results shows that the balancing velocity of the 
magnet fall is inversely proportional to the quadrant of its magnetic 
moment. This work may be useful for experts in the area of the design of 
electromagnetic clutches, brakes, and actuators and for university teachers 
dealing with electrodynamics. Moreover, it can serve as a demonstration of a 
calculation of the field by vector potential, which is an appropriate 
quantity used for the description of magnetic fields.
