Electromagnetic force?

anonymous · Answer

That and magnetic force are the only forces you'd typically expect when you are dealing with electricity

anonymous · Answer

True...but are you sure it is electromagnetic force?

agent0smith · Answer

Was this the question...?

anonymous · Answer

yes.. I am not sure what the formula above represents.

anonymous · Answer

I tried to derive it, but I am not getting the k=mu0/4pi

anonymous · Answer

Could be force between two capacitors.

anonymous · Answer

or conductors?

agent0smith · Answer

^neither of those seem to apply unless each wire or circuit has the exact same current...

anonymous · Answer

in my lab, I used same current for both wires

This is Ampere's Force Law - http://en.wikipedia.org/wiki/Amp%C3%A8re%27s_force_law

anonymous · Answer

got it thanks....
Ampere's force law == electromagnetic force?

ybarrap · Answer

You're welcome

agent0smith · Answer

That's what i started thinking it might be, force between two wires... http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/wirfor.html this didn't have it tho

agent0smith · Answer

Not directly i mean

thank you @agent0smith
