Hi my name is M?sz?ros Istv?n. I've made a computer program which with you can simulate the working of magnets and other elements like shadowing element etc, so you can try out your ideas for magnetic motors.The program is very primitive , and simple , but effective I think. If you want to try It out send me an email to Freegarage@gmail(Dot)com. I'll send you back the program.(java program).This program is made for those who don't have money even for experimenting in their garage.
