Explanation / Answer

    Given that the current is I1 = 3.00 A andI2 = 8.00 A     The separation between the wires is d =10.0 cm = 0.1 m --------------------------------------------------------------------------------- (a) the magnitude of the magnetic field created byI1 at the location ofI2                     B1 = 0*I1 / 2d                           =( 4*10-7 T.m/A)*I1 / 2d                          = ------------ T (b) the force per unit length exerted onI2 by I1                  F / L = 0*I1*I2 / 2d                           = ----------- N/m (c) the magnitude of the magnetic field created byI2 at the location of I1                     B1 = 0*I2 / 2d                           =( 4*10-7 T.m/A)*I1 / 2d                          = ------------ T (d)   the force per unit length exerted onI1 by I2                  F / L = 0*I1*I2 / 2d                           = ----------- N/m                             B1 = 0*I2 / 2d                           =( 4*10-7 T.m/A)*I1 / 2d                          = ------------ T                  F / L = 0*I1*I2 / 2d                           = ----------- N/m
