Homework Statement
Consider the vector potential
A = cr * [(sin theta)^2 * (cos fi) * (sin fi) + (cos theta)^2 ) er
+ (sin theta) cos (theta) * [(sin fi) (cos fi) − 1] e theta
+ {(sin theta) (cosfi)^2 } efi
er: in the er direction
e theta: in the e theta direction
e fi: in the e fi direction
A is given in spherical polar coordinates.
Calculate the line integral A dot dl with closed curve C, where C is the circle parametrised by fi, at some arbitrary values of (r, theta)
Please help, I really can't do this line integral.
It would also be nice to see a full solution!
Can anyone please also tell me what's the general trick of tackling problems with line integral?
Many thanks guys!
