The tolerance for an "origin" in an ordinance scheme is dictated by the tolerance of the overall length and width of the part in relation to whatever features are between.
A hole 6" off the origin ±.005" is no different from an origin point off the hole ±.005". If you want to consider it as the...
Forsure, I understand what you're saying about holding power. In my head, when I 1st questioned this, I wasn't so much thinking in terms of picking up/holding anything with the electromagnet, but more so magnetizing other objects that would pick things up, and manipulating ferrofluid. I probably...
@Electricpete: Thanks for the response!
I'm under the understanding that magnetic fields concentrate around sharp edges. If that's the case, it makes me wonder if a core that came to a sharp point at both ends would be stronger than one that was flat on each side. If not, it must have some...
Assuming the copper winding and overall core dimensions are identical, how does the shape of a core at its ends affect magnetic field strength and shape?
Flat edge VS sharp tip
