What are the three properties of magnets?
1. It will always rest in North-South direction.
2. If a magnet is broken into many small parts then each part will behave as a magnet with North and South Pole respectively.
3. Like poles of magnet repel each other and vice-versa.

Asked in Magnetism
What are 3 properties of magnets?
I learnt in school, there are only two properties of magnet, they are:- 1) Attraction 2) Repulsion I am in middle school and have learned 3. 2 poles North and south Magnetic force (attraction or repulsion) The two poles of the magnets are indivisible.The broken magnets act as independent magnets and posses two poles each .It concludes that magnets are always bipolar.
Is it true that permanent magnets lose magnetism quickly?
permanent magnets are called Ferro magnets. These magnets retain their magnetic properties even after removing of magnetic field. It will have Suceptability > 1. Ex : Iron, cobalt, nickel. Para magnets exhibits magnetism in magnetic field, but loose its magnetic properties when field is removed. Ex : Magnesium, molybdinum, lithium, Tantalum. ~Satish 09555144106
