1 Ketinggian magnet di atas solenoid diukur dengan pembaris, H = 2.0 cm.
The height of the magnet above the solenoid is measured by a ruler, H = 2.0 cm.

2 Magnet dijatuhkan ke dalam solenoid dan bacaan galvanometer dicatatkan = I.
The magnet is dropped into the solenoid and the reading of the galvanometer is recorded = I.
Prosedur
Procedure 3 Eksperimen diulangi dengan ketinggian magnet di atas solenoid yang berbeza,

H = 4.0 cm, 6.0 cm, 8.0 cm dan 10.0 cm.
The experiment is repeated with different heights of the magnet above the solenoid, H = 4.0 cm, 6.0 cm,
8.0 cm and 10.0 cm.
