Which is a sure test attraction or repulsion?

Is attraction a sure test?

If one end is attracted and the other repelled, the metal bar is a magnet. If both ends are attracted, the metal bar is not a magnet. Thus, repulsion and not attraction is a sure test for magnetism.

What is the sure test of the magnets attraction or repulsion?

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 …

Why repulsion is a sure test than attraction?

Repulsion is said to be the sure test to find whether an object is charged or not because attraction can occur between an uncharged body and a charged body due to induction of charges from the charged body to the uncharged body.

What is the sure test of electrification attraction or repulsion?

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.

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.

Is attraction a true test of magnet?

Attraction can be caused either by opposite poles of magnets or between one pole of magnet and an unmagnetised bar of iron whereas repulsion is possible between the two similar poles of magnets. Hence, repulsion is the surest test of magnetism.

Which of the following property is the sure test of magnetism A attraction B repulsion C both A and B D None of the above?

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. So, the correct answer is “Option B”.

Is attraction or repulsion the surest test for magnetization justify your answer?

Attraction can be caused either by opposite poles of magnets or between one pole of magnet and an unmagnetised bar of iron whereas repulsion is possible between the two similar poles of magnets. Hence, repulsion is the surest test of magnetism.

Which is only sure proof of testing the polarity of magnet?

Repulsion is the surest test of polarity and magnetism.

What do we say that only repulsion is a sure test of charge on a body?

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. But the given body is uncharged. Therefore, repulsion is a sure test of charge.

What is the score check of presence of charges repulsion or attraction?

It can only be attracted due to induction of opposite charges on the charged body. However, if the test body is charged, it will be repelled by a tester charge of the same sign. Therefore, repulsion is a sure test for the presence of charge.
