Attempted solution

a. for magnetic field B at point a,

magnetic field, B=U*I/[2*pie*r], where U=4*pie*10^-7, r is the radius, I=current

so, magnetic field at point a is; B= [(4*3.14*10^-7)*10]/[(2*3.14*0)]
therefore B=0 T

b. direction of the mag. field is to the right.

c. magnetic field B at point b,

B= [(4*3.14*10^-7)*10]/[2*3.14*1]= 2*10^-6 T

d. direction of the mag. field is to the left

e. magnetic field, B at point C

B= [(4*3.14*10^-7)*10]/[2*3.14*2]
B=1*10^-6 T

f. direction of the mag. field is up.
