Do the magnetic fluxes of the two coils in the U-shaped electromagnet cancel each other in the intermediate area?
Is there a limit to the number of turns in the coil?
Technically, there is no limit to the number of turns in the coil, but adding more turns can lead to practical limitations such as increased resistance and a larger physical size of the coil. These limitations can affect the efficiency and usability of the electromagnet.
