Question

What happens when the north pole of magnets are placed together?
A. they repel
B. they attract
C. they cancel each other out
D. the strength of the magnet is doubled

Answer 1

Hint: We know that the magnetic field vector force which influences a few magnetic metals. Since it’s a n invisible vector, like other vectors clearly, it has both direction and magnitude. We also know that a magnet has two different poles, namely the North and the South Pole.

Complete step-by-step answer:
A magnet is a small piece of metal that can produce a magnetic field. This piece of metal has two poles, namely the North and the South Pole on the two sides of the metal. Generally, it is said that the like poles attract, while the unlike poles repel.
This is to say that, North Pole of one magnet repels from the North Pole of another magnet. This is true for two South Pole also. However, if two different poles, like a North Pole of one magnet, are brought near the south pole of another magnet, then they attract. This profound property possessed by a magnetic material is also called the magnetic effect.

So, the correct answer is “Option A”.

Additional Information: Also, magnets can be classified into two types on the basis of their magnetic strength namely the permanent and the temporary magnets. A permanent magnet produces a strong magnetic field always, whereas the magnetic field produced by a temporary magnet is short spanned and weak.
Also a freely suspended magnet, oscillates and comes to rest at the geographical north-south direction.

Note: We know that the magnetic field is a vector quality, and hence has both direction and magnitude. We can also say that the direction of the magnetic field is given from north to south outside the magnet and from south to north inside the metal.
