This reeks of homework thread.

And then here

Then F = grad( m \cdot B ) and bubs yer oncle

Nah dude, I just care about the magnitude. I want to do a project which would only make sense if I could get at least 10N of force on this. You can't actually calculate a concrete number without a wire diameter and most likely a current.

>>1154249
Shit, thanks. Will try to work it out from that.

>>1154247
Depends on wire diameter and batteries, but 0.1N is the most reasonable guess of those 3.

>>1154249
This doesn't take into account the relative magnetic permeability though. Or am I just missing something? (I'm not in Engineering, nor any related profession).

>>1154261
Well fuck. Thanks. Kind of hoped it would be at least around 1N.

>>1154265
> The relative permeability of magnetic iron is around 200

Nigga dint even scroll

>>1154271
Yeah that, that's weird though, Google says permeability for iron (pure) should be 5000, not 200.

Almost forgot - just so you know this is not for a homework - I was thinking if it would be possible to build artificial muscle fibers using electromagnets in series like sarcomeres..

It's not that hard really
