Magnets have two poles north and south.

Like poles repel and unlike poles attract.

There are 2 properties of magnets.


I learnt in school, there are only two properties of magnet, they are:-1) Attraction2) RepulsionI am in middle school and have learned 3.2 poles North and southMagnetic 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.


Magnets lose their magnetic properties if they are droped down from a height and when they are heated.


False. You'll have two magnets with each a north and a south pole.


Opposite poles of magnets attract each other while like poles repel. So... North is attracted to South but two Norths repeal and two Souths repel. Magnets are also attracted to magnetic substances such as Iron and Nickel. Basically, magnets have two poles, they come in various shapes and attract/repel other magnets.



The two main properties of salt are being soluble in water and being made of at least two elements. Salt is not a pure substance due to these properties.



they have magnetic properties that weaken with time.


magnitisam X4 in the bush


if magnets are heated in temperatures above 760 c they lose their magnetic properties


Permanent magnets, such as magnetite or rare-earth elements, retain their magnetic properties perpetually, while temporary magnets exhibit magnetic properties only when affected by a magnetic field produced by an electric current or another permanent magnet.


all magnets have two poles


PROPERTIES OF MAGNET1. Magnets attract objects of iron, cobalt and nickel.2. The force of attraction of a magnet is greater at its poles than in the middle.3. Like poles of two magnets repel each other.4. Opposite poles of two magnets attracts each other.5. If a bar magnet is suspended by a thread and if it is free to rotate, its South Pole will move towards the North Pole of the earth and vice versa.


repel force, attraction force,


i believe it is mass and volume. :)



Two household objects that have magnets are: fridge magnets, and sizzlers


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



By properties they are Thermosetting plastics and Thermoplastics


When two magnets are brought close to each other and they try to move apart, we say the two magnets each orher


Once magnetized, permanent magnets retain their magnetism properties. On the other hand, temporary magnets lose their magnetic ability once they are out of a magnetic field.


No. Its properties are different from those of iron or sulfur.


Magnets can lose their magnetic properties if exposed to high heat or are made subject to high impact. The temperature at which magnets lose magnetic properties is referred to as the Curie Temperature for ferromagnetic materials.
