Is a sure test of magnetism than attraction?
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 …
Is attraction a true test of magnetism?
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.
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 .
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.
Why do magnetic monopoles not exist?
A magnetic monopole does not exist. Just as the two faces of a current loop cannot be physically separated, magnetic North pole and the South pole can never be separated even on breaking a magnet to its atomic size. A magnetic field is produced by an electric field and not by a monopole.
Does magnetic energy always cause attraction?
Answer: true magnetic energy always cause attraction.
Why not attraction but repulsion is the sure test of magnetism?
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.
How do you test for magnetism?
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.
