Question

Which of the following is an example of types of magnets based on shape? (This question has multiple correct answers)
A. Horseshoe magnet
B. U shaped magnet
C. Bar magnet
D. Electromagnet

Answer 1

A magnet is metal that can produce a magnetic field. A magnet has two different poles, namely the North and the South Pole on two sides of the metal. These metals show a special property called the magnetic effect.

Complete step by step answer:
We know that the magnetic field is an invisible force which is a vector that influences an electric charge and a few magnetic metals. Since it’s a vector clearly, it has both direction and magnitude. A magnet has two different poles, namely the North and the South Pole. Generally, the like poles attract, while the unlike poles repel. This is saying that, North Pole of one magnet repels from the north pole of another magnet, this is true for two South Pole also. However, if a North Pole of one magnet is brought near the south pole of another magnet, then they attract.
There are two types of magnets 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 magnets come in different shapes, for example horseshoe or the U shaped magnet, disc magnets, sphere magnets, bar magnets and many more. The shape of the magnets also affects the magnetic field produced by them.
Hence the answer here is , A. horseshoe magnet, B. U-shaped magnet, C. bar magnet

Note:
Electromagnet is also a type of magnet. We know that flow of charges in a conductor produces magnetic fields around the conductor. Electromagnets are produced when flowing current induces a magnetic field on a piece of metal. Example is solenoid. Clearly, the option electromagnet differs from other by the means of production, while others use different types of magnets.
