Question

Similar poles ____ and opposite poles ____. Fill in the vacant space with relevant words.
A) Repel, attract
B) Attract, repel
C) Attract, attract
D) Repel, repel
E) Rebel, attach

Answer 1

Hint:Looking at the options it is clear that the E) option is a misprint. Magnetic poles is the region at the end of each magnet. There are two poles of magnets, North and South. Earth has its own magnetic poles. It is to be noted that the magnetic poles of Earth are changing and also the poles of Earth at times interchange.

Complete answer:
Let’s look at the definition of a magnet: A magnet is a material which is capable of producing a magnetic field and attracting unlike poles and repelling like poles. The answer to our question is given in the definition of magnet itself.

As we know, the properties of magnets: Magnets are known to attract some metals. Magnets are capable to induce magnetism in ferromagnetic, diamagnetic substances.Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges.

We also know that magnetic poles exist in pairs and when a magnet is suspended freely, the North Pole of the magnet points to the South Pole of the Earth and vice versa.

Electromagnets are used in heavy industries to pick heavy metal objects. Magnets attract or repel due to the force of magnetism.

Note:As we know, magnetism was discovered and not invented and it must be noted that magnetic poles always exist in pairs. It is practically not possible to separate the two poles of the magnet. Similarly it is not possible to have magnets with identical poles. Magnets attract other metals by inducing magnetism in that metal and with the help of its magnetic field.
