Question

open image in window for question.

Consider the following configuration of currents. The straight line current is tangential to the circular loop current. Take I1=4A and I2=2A. Determine the magnitude and the direction of the magnetic fields due to the circular loop current I1 at the center of the circle. Determine the magnitude and the direction of the magnetic fields due to the circular loop current I2 at the center of the circle If the net magnetic fields at the center of the circle is zero what is the direction and magnitude of I3? Find the magnetic force per length acting on I3 due to I2. (Both direction and magnitude.)

Explanation / Answer

a. magnetic fiedl at centre due to I1 is B1 = u0I1/2R

direction is obtained by amperes RH rule as perpendiculsarly out of the paper

b. magnetic field at R due to I2 is B2 = u0I2/2piR

direction is outward o the paper

c. for net field to be zero, equal magnitudes of fields must act in opposite direction

so B will be inwardc into papaer

so that i will be towards the left side

d. magnetic force per unit length F/L = u0I1I2/2piR

in a driection towards the I1
