## Why Repulsion is the surest test of electrification?

Repulsion is considered as the true test of electrification. This is because repulsion is observed only when two bodies have like charges and this means that the bodies must be charged. Hence, repulsion is a true test of electrification.

What is the surer test of magnetism Class 10?

What is the surer test of magnetism? Repulsion is the surer test of magnetism.

How will you prove that the property of attraction is more at the two ends of magnet?

Observation: If the two poles you are trying to bring closer are the same ie. Both are North poles or both are south poles, then the two poles will repel each other. If you are trying to bring the opposite poles together there will be a force of attraction between the two magnets.

### What does the term repulsion mean in magnetism?

The force between two wires, each of which carries a current, can be understood from the interaction of one of the currents with the magnetic field produced by the other current. It is repulsive if the currents are in opposite directions. …

Which test is not the surest test to know the presence of charge on a body?

Attraction is not a sure test to detect presence of charge on a body.

What does an electric charge in uniform motion produces?

Hence, when an electric charge is in uniform motion, it produces an electric field that is also changing in position and travelling through space. Thus, this changing electric field produces a changing magnetic field. Hence, the electric charge in uniform motion produces both electric and magnetic fields.

#### Why is it said that repulsion is a sure test of magnetism How would you distinguish between a magnet and a bar of a magnetic material by using this test?

A: Repulsion is a sure test of magnetism. B: Magnetic induction precedes attraction.

Which of the two attraction or repulsion is a sure test of magnetism?

Therefore, with the attraction of two materials we cannot determine whether both of them act as magnets or show magnetism. Whereas, repulsion only occurs between the like poles of two magnetic substances. Therefore, repulsion is the sure test for magnetism.

What causes magnetic attraction and repulsion?

Inside the iron bar are tiny magnetic regions called domains. When a strong magnet is present, these domains line up with most of the north seeking ends in the same direction. When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion.

## What does repulsion mean in chemistry?

(noun) a force that moves two bodies away from each other.
