Deflection of β particles in a magnetic field and data-logging

There is an increasing awareness amongst teachers, and students alike, of the potential benefits of using microcomputers in the school science laboratory. Ever since the advent of microcomputers with datalogging facilities, conventional experiments are being done in exciting and novel ways. The case for using micros effectively in the class has been well argued by Laurence Rogers.1 In this article, the methodology adopted by an A-level student tackling an experiment on the deflection of β particles is analysed to ascertain the likely advantages of automating this experiment.
