Hello For an electromagnet of given dimensions of coil, to have most possible field what is the best? to increase the number of turns for less current either to decrease the number of turns and to increase the cross section of conductor and increase the current value: nXI with 10A x 100 turns...
Excuse my poor language.I live in France. My hobby is magnetic suspension/levitation. I would like to make a variable magnet very powerfull. Because the Joule effect in copper magnet wire I imagined to take a big permanent magnet 3"x3"N48 and to place it on the iron right core of a...
Hello, For a given magnetic volume and the same grade ( for example N48) to have the biggest possible force, is it preferable to use a single big magnet wich makes the volume either use a pile (stack) of several magnets to make the same volume? thank you.
