Properties of Magnet

Back

1.Magnet attracts magnetic materials like iron and steel.

2.Magnet has the strongest magnetic strength/pull/attraction at the two poles.

(Do not write: Magnet is the strongest at its ends

3.A freely suspended / floating magnet always points in the North-South direction.

Front

Interactions between magnets

Back

When the unlike poles of the magnets are facing each other, they attract.

 

When the like poles of the magnets are facing each other, they repel.

Front

Interactions of magnet with other magnet, magnetic materials and non-magnetic material.

Back

Magnet interacts with another magnet: The magnet will repel another magnet when their like poles are facing each other.

 

Magnet interacts with a magnetic material: The magnetic material will only be attracted to the magnet.

 

Magnet interacts with a non-magnetic material: The non-magnetic material is not attracted to the magnet.

How to make a magnet with

Stroking Method

(Part 1)

Back

1. Stroke an iron / steel with one pole of a bar magnet.

2. 2. Repeat the strokes in the same direction using the same pole.

Electrical Method

Back

To increase the magnetic strength of an electromagnet:

1. Increase the number of batteries

2. Increase the number of coils around the object
