Answer 1

Answer #1

here,

as the magnetic field at the center due to straight sections of wire is zero

for the magnetic field at the center

magnetic field = u0 * I/(4R1) + u0 * I/(4R2)

magnetic field = 4pi *10^-7 * 10/(4) * (1/0.10 + 1/0.20)

magnetic field = 4.71 *10^-5 T

the magnetic field at the center is 4.71 *10^-5 T

as the current in the loop is clockwise

the direction of magnetic field at the center is into the plane
