Key Concepts

Magnetic Force on a Current-Carrying Conductor

This concept explains that a conductor with electric current experiences a force when it is placed in a magnetic field. The strength and direction of this force depend on the magnitude of the current, the length of the conductor within the magnetic field, and the orientation of the conductor relative to the field.

Right-Hand Rule

The right-hand rule is a practical guideline used to determine the direction of the force on a current-carrying conductor in a magnetic field. By orienting your right hand so that your thumb points in the direction of the current and your fingers point in the direction of the magnetic field, the perpendicular direction in which your palm pushes represents the force acting on the conductor.

Lorentz Force Law

This law quantitatively describes the force acting on a charged particle or a current-carrying conductor in a magnetic field. It is given by the cross product of the current (or velocity in the case of particles) and the magnetic field vector, indicating that the direction and magnitude of the force are influenced by the angle between these vectors and the respective magnitudes.
