Electric dipoles will receive a moment effect in an electric field, which makes them turn to the parallel direction of the same electric field.

The experiment should be taken with a high-voltage power supply.

Connect the two plates to the positive and negative electrodes of the high voltage power supply, before tuning on the power supply, the paraffin rods of the simulated electric dipoles are turning to any direction without unification. After tuning on the power supply, an electric field appears between the two plates, under the electric field; all the simulated electric dipoles are turning the same direction as the electric field direction. Which shows the polarize phenomenon.
