Torque of a current carrying wire in magnetic field

[richard7893]

For Torque of current carrying wire in magnetic field why does the magnetic field of the current carrying wire itself not contribute to torque?

This is a pretty good piture.

The magnetic field produced by the wire goes around the wire. Since it's not in direct contact with the wire, there will be no torque.

will the current carrying wire experience a force from the magnetic field it produces?... no right?

Correct.
