in PCB when I move a component’s magnet effect, as you take off?
I think you are talking about the “align to grid”? This can be disabled in the View menu.
very good :sorriso:
a little tip:
try to find a small fitting grid makes it more comfortable to place your components and wire your board. 
i often use grids like 0.0125 inch. if you work on a 0.1 inch basis this is very cool
