Description: A cyclotron is a device for accelerating charged particles to high speeds as they follow an expanding spiral path. The charged particles are subjected to both an electric field and a magnetic field. One of these fields increases the speed of the charged particles, and the other field causes them to follow a curved path. Which field performs which function?

Key Concepts

Cyclotron

A cyclotron is a type of particle accelerator that uses combined electromagnetic fields to accelerate charged particles along a spiral path. It illustrates the practical application of electromagnetic theory by using an alternating electric field to accelerate particles and a perpendicular magnetic field to bend their trajectory.

Electric Field

An electric field is created by electric charges and exerts a force on other charged particles. In the context of a cyclotron, the electric field is responsible for imparting energy to the particles, thereby increasing their speed as they pass through the accelerating gap between the device’s components.

Magnetic Field

A magnetic field is generated by moving charges or magnets and influences the motion of moving charges by exerting a force perpendicular to their velocity. Within a cyclotron, the magnetic field bends the path of the accelerated charged particles, causing them to move in a curved, often circular or spiral, trajectory.

Lorentz Force

The Lorentz force is the combined effect of electric and magnetic fields on a charged particle. It explains how the electric field accelerates the particle, and the magnetic field alters its direction, thus serving as the theoretical foundation for the workings of devices like cyclotrons.
