Function of electric and magnetic fields in a cyclotron?

We purchased it and tried magnetic power right here, we discovered: question by lucia surfing ? Function of electric and magnetic fields in a cyclotron A cyclotron is a device for accelerating charged particles to high speeds in circular orbits of growing radius. The charged particles are subject to each an electric field and a magnetic field. One of these fields increases the speed of the particles, and the other field maintains them on a circular path.
