Has anyone seen this? know anything about it?https://www.youtube.com/watch?v=fnWuPzAKigsI find it very interesting, comments please those who are into magnetic inductionregardsMike
love the guy's heat test method-i just used my fingers to see how hot the coil got lol.
They say that PM's cant do useful work--> i say remove them from your PM DC motor,and see how useful it is now.
Its the current in the coil that does the business.
You can have all the current you like,but without anything for that magnetic field to grab onto,it would simply be a heater.Replace the PM's with blocks of steel insted,and watch most of your torque in your PM motor disappear. Like i said,nothing is attracted(or repelled) to an electromagnet more than a PM-->nothing comes close.
