Homework Equations
B=I x 10^-7 (Integral sign) sinΘ/r^2 dl
The Attempt at a Solution
B= I x 10-7 (Integral sign) sin Θ /r^2 rdΘ/sin0
B= I x 10^-7/0.0200 (Integral sign) sinΘ dΘ
B=.5 x 10^-7 [-(-2)-(-5)] = ??
Does anyone have a real good document on how to Find flux density at a point? My current book does not fully explain it. Is there a online calculator that would help?
Thanks.
