Homework Statement
suppose that mag field is B=kz [tex]\stackrel{^}{x}[/tex]
find force on a square loop(side a) lying in the yz plane and centers at origin, if it carries a current I flowing counter clock whne u look down x axis
Homework Equations
Fmag=I[tex]\int[/tex](dl x B)
The Attempt at a Solution
Why does The force on the left side (toward
the left) cancels the force on the right side (toward the right)? Also than the answer is
netforce= 2(IaB)=2(Ia(ka/2)=Ia2k up
How did B turn into ka/2? and where did the "a" come from?
