A magnet always attracts objects like iron, nickel, cobalt.
With the experiment with iron filling the can conclude that the Iron filling gets attracted near the ends of the magnets. These ends are called as Poles of a Magnet.
The attractive property is more at the poles.
Every magnet consists of two poles one is the north pole and other one south pole.
“The magnetic poles always exist in pairs” (Tamil Nadu Government #).
When a magnet is broken into two pieces, each piece behaves as a separate bar magnet.
When a magnet is vertically split, the length of the altered and each piece acts as a magnet.
When a magnet is horizontally split, the length of the new pieces of magnet remains unaltered and there is no change in their polarity.
In both cases, the strength of the magnet is reduced.
Repulsive Property
Like poles repel and unlike poles attract each other.
That is north pole attracts south pole and south pole attracts the north pole.
And North pole repels the north pole and south pole repels the south pole.
Directive Property
A suspended magnet always points towards the North-South Direction.
The freely suspended magnet always aligns itself to the North-South Direction and this property is called as the Directive property of magnet.
The north pole of the bar magnet always points towards the North and south pole of the bar magnet always points towards the south.
