find the magnetic force acting on the wire.

Two parallel horizontal conductors are suspended by two light vertical threads each 75 cm long. Each conductor has a mass of 40 g m^-1 and when there is no current they are 0.5 cm apart. Equal current in the two wires result in a A long straight rigid wire carrying a current is kept co-axially [...]

Two long parallel wires carry currents of equal magnitude but in opposite directions. These wires are suspended from rod PQ by four chords of same length L as shown in figure . The mass per unit length of the wires A long straight rigid wire carrying a current is kept co-axially with the current carrying [...]

A straight conductor of length r0 carrying a current i is placed perpendicular to a long straight conductor which carries a current i0 as shown in the figure. Find the force of interaction between them. A long straight rigid wire carrying a current is kept co-axially with the current carrying long thin plane which is [...]

A long straight rigid wire carrying a current is kept co-axially with the current carrying long thin plane which is bent in the form of a circular arc. If the inward current i flows through the plate, find the magnetic force acting on the wire. A long straight rigid wire carrying a current is kept [...]
