Explanation / Answer

(a)

Magnetic field strength at point a,

Ba = (u0*l1 / 2*pi*r1) - (u0*l2 / 2*pi*r2)

Ba = (4*pi*10-7 / 2*pi) * (8 / 0.02 - 8 / 0.06)

Ba = 5.33*10^(-5) T

(b)

direction of magnetic field at point a - out of the page

(c)

Magnetic field strength at point b,

Bb = (u0*l1 / 2*pi*r1) + (u0*l2 / 2*pi*r2)

Bb = (4*pi*10-7 / 2*pi) * (8 / 0.02 + 8 / 0.02)

Bb = 16*10^(-5) T

(d)

direction of magnetic field at point b - into the page

(e)

Magnetic field strength at point c,

Bc = (u0*l2 / 2*pi*r2) - (u0*l1 / 2*pi*r1)

Bc = (4*pi*10-7 / 2*pi) * (8 / 0.02 - 8 / 0.06)

Bc = 5.33*10^(-5) T

(f)

Direction of magnetic field at point c - out of the page
