A current carrying wire does not tend to rotate in a magnetic field. What do you conclude from this?

How is a current - carrying wire placed in a magnetic field so that a magnetic field does not act on it ?

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

What happens when a current carrying wire is placed in a magnetic field?

Magnetic field due to a long current-carrying wire Oersted's experiments showed that there is a magnetic field around a current-carrying wire. We determine the magnitude of magnetic field at some distance from a long stright wire carrying a current I.

The ratio of the magnetic field at the centre of a current carrying circular wire and the magnetic field at the centre of a square coil made from the same length of wire will be
