The net charge in a current carrying wire is zero. Them, why does a magnetic field exert a force on it?

A current carrying loop lying in a magnetic field behaves like a ….

A long straight conductor carrying a current lies along the axis of a ring. The conductor will exert a force on the ring, if the ring

Prove that the force acting on a current carrying wire, joining two fixed points a and b in a uniform magnetic field, is independent of the shape of the wire.

The force between two parallel current carrying wires is independent of

The free electrons in conducting wire are in constant thermal motion. If such a wire, carrying no current, is placed in a magnetic field, is there a magnetic force on each free electron? Is there a magnetic force on the wire?

Starting from the expression for the force on a current carrying conductor in a magnetic field, arrive at the expression for Lorentz magnetic force.

A very long bar magnet is placed with its north pole coinciding with the centre of a circular loop carrying an electric current. i . The magnetic field due to the magnet at a point on the periphery of the wire is B . The radius of the loop is a . The force on the wire is

A circular loop of radius r carries a current i. where should a long , straight wire carrying a current 4i be placed in the plane of the circle so that the magnetic field at the centre becomes zero?
