Two wires carrying equal currents i each, are placed
perpendicular to each other, just avoiding a contact. If
one wire is held fixed and the other is free to move under
magnetic forces, what kind of motion wil results?

Two long wires, carrying currents i_1 and i_2, are placed perpendicular to each other in such a way that they just avoid a contact. Find the magnetic force on a small length dl of the second wire situated at a distance l from the first wire. (figure)

A 3*0cm wire carrying a current of 10A is placed inside a solenoid perpendicular to its axis. The magnetic field inside the solenoid is given to be 0*27T . What is the magnetic force on the wire?

Two long wires each carrying a d.c. current in the same direction are placed close to each other. Which one of the following statements is correct?

Three infinitely long wires, each carrying a current 1A, are placed such that one end of each wire is at the origin, and, one of these wires is along x-axis, the other along y-axis and the third along z-axis. Magnetic induction at point (-2 m, 0, 0) due to the system of these wires can be expressed as

Consider a wire carrying a steady current, I placed in a uniform magnetic field vecB perpendicular to its length. Consider the charges inside the wire. It is known that magnetic forces do not work. This implies that

Three long wires, each carrying current i are placed parallel to each other. The distance between I and II is 3d , between II and III is 4d and between III and I is 5d . Magnetic field at site of wire II

A segment AB of wire carrying current I_1 is placed perpendicular to a long straight wire carrying current I_2 as shown in figure. The magnitude of force experieced by the straight wire AB is

There straight current carrying conductors A,B and C are placed parallel and adjacent to each other by an electrician as shown in the figure. Then determine the direction of resultant force acting on the wire B .
