Magnetic deflection refers to the change in the trajectory of charged particles when they pass through a magnetic field, due to the Lorentz force acting perpendicular to their velocity and the magnetic field. This principle is fundamental in devices like mass spectrometers and cathode ray tubes, where it is used to analyze particle properties based on their deflection patterns.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. It is generated by electric currents and magnetic dipoles, and is characterized by both a direction and a magnitude, which can be visualized through field lines that extend from the north to the south pole of a magnet.

The Lorentz Force is the force experienced by a charged particle moving through an electromagnetic field, combining the effects of both electric and magnetic fields. It is fundamental in electromagnetism and is described by the equation F = q(E + v × B), where F is the force, q is the charge, E is the electric field, v is the velocity, and B is the magnetic field.

Cathode Ray Tubes (CRTs) are vacuum tubes that produce images when electron beams are directed onto a phosphorescent screen, once widely used in televisions and computer monitors before the advent of flat-panel displays. Their operation is based on the manipulation of electron beams and magnetic fields, which allows for the rendering of images through controlled illumination of the screen's phosphor coating.
