When a conductor carries current, it means that charges (typically electrons) are in motion inside the conductor. A magnetic field exerts a force on these moving charges , not on stationary ones. This force is given by the Lorentz force law : 
This interaction causes the entire conductor to experience a mechanical force when placed in a magnetic field.
