Question

Two long, parallel conductors, separated by 13.0 cm, carry currents in the same direction. The first wire carries a current I₁ = 3.00 A, and the second carries I₂ = 8.00 A. (See figure below. Assume the conductors lie in the plane of the page.)

(a) What is the magnetic field created by I₁ at the location of I₂?
magnitude Tdirection ---Select--- in the +x direction in the -x direction in the +y direction in the -y direction in the +z direction in the -z direction
(b) What is the force per unit length exerted by I₁ on I₂?
magnitude N/mdirection ---Select--- in the +x direction in the -x direction in the +y direction in the -y direction in the +z direction in the -z direction
(c) What is the magnetic field created by I₂ at the location of I₁?
magnitude Tdirection ---Select--- in the +x direction in the -x direction in the +y direction in the -y direction in the +z direction in the -z direction
(d) What is the force per length exerted by I₂ on I₁?
magnitude N/mdirection ---Select--- in the +x direction in the -x direction in the +y direction in the -y direction in the +z direction in the -z direction
