# Question: What is the sure test of the magnets attraction or repulsion?

Contents

## 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.

## What is the only sure way to test for magnetism?

So by attraction it cannot be surely identified the substance is a magnet or not . So , repulsion is the sure test of magnetism .

## What is the reliable test for magnet?

Flux Density Check

This test uses a gaussmeter to measure the flux density of a magnet at a determined distance. Typically, the measurement is made either at the magnet’s surface or at the distance at which the flux will be used in the magnetic circuit.

## Why is repulsion sure tested?

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. … Hence repulsion is the sure test to find whether an object is charged or not.

## Why is repulsion a sure 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 sure test of magnetism Class 10?

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.

## 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.

## Why do we say that only repulsion is a sure test of charge on a body class 8?

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.

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

Repulsion is the surest test of polarity and magnetism.

## Is the most reliable test for magnetism?

In case of magnets, repulsion occurs only between like poles. Therefore, repulsion is the most reliable test for magnetism.
