5. Many hospitals use a cyclotron to produce radioactive isotopes for nuclear imaging or nuclear medicine. A cyclotron uses a strong magnetic field to keep protons moving in circular orbits. A proton begins in a small-diameter orbit with a low speed, but it is gradually accelerated with a clever use of electric fields to higher and higher speeds. This causes the orbit's diameter to gradually increase until the proton exits the machine from a large-diameter orbit. One commercial cyclotron uses a 2.0 T magnetic field.
