Q21:Two long, parallel conductors, separated by cm, carry currents in the same direction. The first wire car- ries a current I 1 = A, and the second carries I 2 = A.
(a) What is the magnitude of the magnetic field created by I 1 at the location of I 2?
(b) What is the force per unit length exerted by I 1 on I 2?
(c) What is the magnitude of the magnetic field created by I 2 at the location of I 1?
(d) What is the force per length exerted by I 2 on I 1?
