Why does the magnetic force of magnetic steel block decrease in the circumferential direction?
Just when I was visiting a motor forum, I saw a problem about magnets. The problem is that if the magnet steel is divided into blocks according to the circumferential direction, why does the magnetic force decrease at this time? The simulation result shows that the thickness of the permanent magnet needs to be thickened to achieve the overall effect of the magnet steel before. What’s the matter?
As we have not carried out relevant experiments to measure the magnetic force, we can not present the results in a more intuitive way. We have temporarily sorted out the replies of two engineers, hoping to be helpful to you.
