18M.3.SL.TZ1.a

A magnetized needle is oscillating on a string about a vertical axis in a horizontal magneticfield B. The time for 10 oscillations is recorded for different values of B.

M18/4/PHYSI/SP3/ENG/TZ1/01_01

The graph shows the variation with B of the time for 10 oscillations together with the uncertainties in the time measurements. The uncertainty in B is negligible.

Draw on the graph the line of best fit for the data.
