- With current switched off record the initial reading of spring balance (Fo)
- Vary the current (I) and each time record the corresponding values of I and the force F.
- Tabulate these values.
- For each value of F, subtract F-to get the magnetic force due to the current on the iron (fm)
- Plot a graph of Fm against I.
- The graph will help show the relationship.
