If two straight current carrying wires are kept perpendicular to each other almost touching

Moving Charges And Magnetism

Dear student, here is your solution

I think 4th option will correct

4) The wires will become parallel to each other Reason - Use right hand screw rule to find the direction of magnetic field of wire 1 . It will be into the paper ( perpendicular to the plane of both wires ) . - Magnetic field of wire 1 will apply magnetic force on the wire 2 . Use Fleming's left hand rule to check the direction of this force on wire 2 . It will be downwards . - this downwards force will produce torque on wire 2 and will rotate it by 90 degrees . Due to the rotation; wire 2 will become vertical or we can say it will be parallel to wire 1 .

( Wire 2 will not apply magnetic force on 1 because direction of magnetic field of 2 and direction of velocity of charges in 1 are opposite so force will be 0 if we use formula F = qvBsin(theta) as theta=180 )

. Two long current-carrying wires run parallel to each other. Show that if the currents run in the same direction, these wires attract each other, whereas if they run in opposite directions, the wires repel.

20. If two straight current carrying wire are kept perpendicular to each other almost touching , then the wires will a. Attract b. Repel c. Remain stationary d. Become parallel .
