Attractive Property
- 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.
