I am interested in mechatronics or electrical engineering, and I enjoy things such as electronics and programming as a hobby, mechanics as well.
I do however, have some mild essential tremor, which means that my hand trembles slightly when I move it(not parkinson's, this is benign). Although...
Thanks, that was exactly what I was looking for.
So am I right in saying that if a metal object entered and left a magnetic field, by the time it leaves the magnetic field, there is no net energy gained?
Since magnets cannot be "switched off" without input energy, energy cannot be gained from them(right?).
But how do you explain and prove this? If I wanted to tell an inventor attempting to find free energy, how would I explain this to him/her?
