When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion. The rule for magnets is that like poles repel and unlike poles attract.
Correspondingly, what are 5 examples of magnets?
Common uses of magnets include the compass, vending machines, refrigerator magnets and electric motors. Some types of trains even levitate above magnetized rails! Without magnets, the world would be a very different place.

Hereof, what causes magnetic repulsion?
Magnetism Repel and Attract Definition
If it moves in the other direction, then the v value must be negative. These two particles repel each other if the magnetic forces determined by their respective magnetic fields between them cancel each other out by pointing in different directions away from one another.
What is an example of magnetic attraction?
For example, computer hard drives, flash drives, floppy drives, zip drives. magnetic pole: One of the two ends of a magnet where the magnetic field is most intense. repel: To push back or away by a force.
What is attraction and repulsion of a magnet?
When two magnets are moved close to each other, they either attract or repel each other. The opposite poles of magnets attract, whereas the similar poles of magnets repel when they are pulled towards each other. Attraction or repulsion of the magnets depends on the direction of the poles facing each other.
What is attraction and repulsion?
Attraction is a force between two or more dissimilar or unlike charges. Two charges of dissimilar characteristics pull towards each other. Repulsion is a force between two or more similar or like charges. Two charges of similar characteristics pull away from each other.
What is the attraction or repulsion of magnetic materials?
The force of attraction or repulsion of magnetic materials.
What is the difference between a magnets attraction and repulsion?
The attraction between magnets is a little stronger than the repulsion. That is due to the alignment of the molecular magnets in the magnet. The attraction as well as the repulsion of magnets decrease significantly with increasing distance.
What is the example of magnetic force for Class 8?
Examples of magnetic force
When we close the door of a refrigerator, and the door comes close to the fridge, it gets pulled by a strong force. As a result, the door closes. It is the magnetic force that pulls the door. Cranes are fitted with electromagnets, which are temporary magnets.
