Why repulsion is a sure test?

Why repulsion is a sure test?

Repulsion is the sure test for magnetism because it occurs only when two like poles of a magnet exist while the attraction phenomenon can occur between two unlike poles of a magnet and also between a magnet and a magnetic material means if there are two magnets they will attract each other and suppose if one material …

What is the sure test of electricity?

Attraction may occur between two oppositely charged bodies or a charged body and an uncharged one. That is why in attraction, one is not sure if both bodies are charged, However in repulsion, there are two bodies that have the same charge. That is why repulsion is the sure test of electrification.

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.

Why do we say that repulsion is a short test of charge on an object?

Because when we bring a charged body near an uncharged body an opposite charge is induced on the neutral body. And their will an attraction between them. Therefore, repulsion is a sure test of charge. …

What is electrification mention the methods of electrification?

The process of developing charge in a body is called electrification. An object can be electrified by differentmethods which are by friction, by conduction, and by induction.

Why repulsion is sure test of magnetism but attraction is not?

Repulsion can only take place between two like poles of a magnet. By attraction, one can not say if a substance is magnetic or not, but if two objects repel each other, one can be sure that those two objects are magnets. Hence, Repulsion is the sure test for magnetism.

Which is the sure test of magnetism :- 1 Attraction 2 Repulsion 3 Polarisation 4 None of these?

Therefore, repulsion is the sure test for magnetism.

Which is the sure test of magnetism 1 attraction 3 Polarisation 2 repulsion 4 None of these?

What does the word electrification mean?

verb (used with object), e·lec·tri·fied, e·lec·tri·fy·ing. to charge with or subject to electricity; apply electricity to. to equip for the use of electric power, as a railroad. to excite greatly; thrill: to electrify an audience.

Why do we take repulsion as a test of electrification?

Attraction can takes place b/w neutral bodies due to induction. But two bodies will repel only if they have opposite charge so we take repulsion as sure test of electrification. Repulsion is sure to test of charge of a body because of it indicates that the other object is charged and has charge opposite to that of first object.

Why is repulsion a sure test of the nature of charge?

Because when we bring a charged body near an uncharged body an opposite charge is induced on the neutral body. And their will be an attraction between them. But the given body is uncharged. Therefore, repulsion is a sure test of nature of charge.

Which is the sure test of electrification than attraction?

While electrostatic force of repulsion between two bodies are observed only when they have like charges. That is both the bodies must be charged. Thus, repulsion is the sure test of electrification than attraction.

What is the difference between attraction and repulsion?

Attraction may occur between two oppositely charged bodies or between a charged body and an uncharged one. That is why, in attraction, one is not sure whether both bodies are charged. However, in repulsion, there are two bodies that have the same charge. That is why repulsion is the sure test of electrification.
