How do you do an experiment to investigate how magnetic flux affects the angle through which beta particles are deflected?

You need to have some method of measuring the angle, such as a 360 degree protractor; a hall probe; a way to remove radiation, such as some paper; beta radiation; and the current in the Helmholtz must be changed to vary the magnification field density. Be sure to repeat readings, calibrate the hall probe, keep the separation of the coils constant, and correct the deflection of beta radiation on the diagram.
