In this problem, we have a combination of the magnetic field due to straight currents and loops.
Magnetic field around a wire carrying current:
r is the distance from the wire to a point perpendicular to the wire.
The magnetic field produced by a current loop:
r is the radius of the loop
The wire carries current I2, which is 20 times the current I1 of the loop; the direction of the current in the wire is shown. The magnetic field in the center of the loop is zero. The radius R of the loop is 1.5 cm.
A.) What is the direction of the current in the loop?
B.) What is the distance d from the wire to the center of the loop?
