Two long and parallel straight wires A and B carrying currents of 8.0A and 5.0A in the same direction are separated by a distance of 4.0cm. Estimate the force on a 10cm section of wire A.

A long straight wire in the horizontal plane carries a current of 50 A in north to south direction. Give the magnitude and direction of B at a point 2.5 m east of the wire

What is the nature of force between two parallel conductors carrying current in the same direction?

An electron is moving at 10^(6) ms^(-1) in a direction parallel to a current of 5 A, flowing through an infinitely long straight wire, separated by a perpendicular distance of 10cm in air. Calculate the force expected on the electron

A uniform field equal to 1.5T exists in a cylindrical region of radius 10.0cm, its direction parallel to the axis along east to west. A wire carrying current 7.0A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire if : the wire intersects the axis.
