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)

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

Two loops carrying current in opposite sence placed paralled to each other are moved closer to each other. Then the current

An 8 cm long wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. If the magnetic field inside the solenoid is 0.3 T, then magnetic force on the wire is

Two long wires a and b, carrying equal currents of 10*0A, are placed parallel to each other with a separation of 4*00 cm between them as shown in figure. Find the magnetic field B at each of the points P,Q and R.

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?

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

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

If each of the two lines is perpendicular to the same line, what kind of lines are they to each other?
