Learning Outcomes

Recognise that a magnet can exert a push or a pull and unlike poles attract and like poles repel

Description

This simulation shows how the polarity of the electromagnet changes with the direction of the battery placed in the circuit.

The north seeking pole (N-pole) of the magnet is indicated as N, while the south seeking pole (S-pole) of it is indicated as S.

Initially, the battery faces the left side, inducing a north seeking pole (N-pole) on the right side of the iron rod.

The user is able to drag the magnet. When the magnet is close enough, it will be attracted/repelled to/by the iron rod accordingly.

The following are the controllable variables:

The object used to identify the poles of the electromagnet, from Magnet NS to Iron bar, to Magnet SN.

The side of the battery changing from left to right.

The object is moveable in the x-axis direction.

Reset Button will put the simulation back to its default state.
