Does one part of a wire carrying curent exert a force on another part of the same wire?

Is a wire carrying current charged?

A rectangular loop of wire of size 4 cm xx 10 cm carries a steady current of 2A. A straight long wire carrying 5A current is kept near the loop If the loop and the wire are coplanar, find (i) the torque acting on the loop and (ii) the magnitude and direction of the force on the loop due to the current carrying wire(fig).

Two parallel wires carrying currents in the same direction attract each other because of:

A uniform magnetic field of 1.5 T exists in a cylindrical region of radius10.0 cm, its direction parallel to the axis along east to west. A wire carrying current of 7.0 A 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.

Electric current through the straight horizontal part of a wire is flowing from east to west. The force experienced by this part of the wire due to earth's magnetic field will be such as to pull it:

In what respect does a wire carrying a current differ from a wire, which carries no current?
