Magnetic deflection of radiations


The diagram shows how alpha, beta and gamma radiation would be deflected by a magnetic field acting perpendicular to the path of the particles.

Alpha particles are deflected a little because of their large mass while beta particles are deflected much more because they are nearly two thousand times lighter. They have a negative charge while alpha particles are positive and so they are deflected in the opposite direction.

Notice that the gamma rays are not deflected at all this is because they have no charge.

In the diagram the magnetic field acts into the plane of the paper.
