Two infinite sheets carrying current in same direction (of equal current per unit length K) are separated by a distance d. A proton is released from a point between the plates with a velocity parallel to the sheets but perpendicular to the direction of current in the sheets. Then the path of the proton is

Two long parallel conducting wires carry current I in same direction, placed at distance b. Force per unit length of wire is

Two long parallel copper wires carry current of 5A each in opposite directions. If the wires are separated by a distance distance of 0.5m, then the force per unit length between the two wires is

Two infinitely long parallel wires carry equal current in same direction. The magnetic field at a mid point in between the two wires is

When two parallel wires carrying current l and 2l in same direction are placed at a distance d apart, the ratio of force per unit length acting upon the wire due to other is

Define SI unit of current in terms of the force between two parallel current carrying conductors. (b) Two long straight parallel conductors carrying steady currents I_(a)andI_(b) along the same direction are separated by a distance d. How does one explain the force of attraction between them ? If a third conductor carrying a current I_(c) in the opposite direction is placed just in the middle of these conductors , find the resultant force acting on the third conductor.
