A current-carrying coil produces a magnetic field.
It is suggested that the strength of the magnetic field at the centre of a flat circular coil is inversely proportional to the radius of the coil.
Design a laboratory experiment that uses a Hall probe to test the relationship between and . You should draw a diagram, on page 3, showing the arrangement of your equipment. In your account you should pay particular attention to
(a) the procedure to be followed,
(b) the measurements to be taken,
(c) the control of variables,
(d) the analysis of the data,
(e) the safety precautions to be taken.
