what do you mean
2 N lea R ki Consider a loop of conducting wire with radius a in the ry plane, carrying a current I(tr) = kt. Consider further a point 7 which is a small distance away from a point To on the z axis, i.e. ✓ = 8+5r with 0 os -- 0 z. or Oy 8. and (8.2,84,82) « z. Let o= 77 - where = a cos o f + a sin oġ is a point on the wire loop - see the Figure above. a) To first (i.e., linear) order in 8,/R, < 1, 8,/R, « 1, and 8/R, < 1, find an approximate expression for the scalar (V) and vector À potentials at the point 7 (i.e., in the vicinity of ). b) Use the result from a) to calculate the electric (E) and magnetic (B) fields at the point ro.
