Electric field: The direction of motion of a conductor in an electric field is determined by the polarity of the electric field and the charge on the conductor.
Magnetic field: The direction of motion of a conductor in a magnetic field is determined by the polarity of the magnetic field and the current present in the conductor.
Friction: Friction between the conductor and the surface on which it is moving can also influence the direction of motion of the conductor.
Gravity: If a conductor is moving in a gravitational field, the direction of motion of the conductor will be determined by the strength of the gravitational field and the mass of the conductor.
Temperature: Temperature can also influence the direction of motion of a conductor by changing its viscosity, density and electrical properties.
Pressure: Pressure can also influence the direction of motion of a conductor by changing its electrical properties and causing it to move along a particular path.
