My question is, if I have so system like square loop... and all the donations be summed up by Bcos(Tetha) or sin(Tetha), am I need to multiply the cos/sin in Biot -Savart rule?

So I will get

dB=const*dx * sinTetha*

**cosTetha**/ r^2

or I just need to exchange cos with sin? (if all donations are summed up with BcosTetha)

?

Thanks for watchers and answerers !
