Question

Magnetite is a/an
A) Natural magnet
B) Electromagnet
C) U shaped magnet
D) None of these

Answer 1

Hint: Here we have asked about magnetite. Like what kind of substance or property it has, whether it’s a natural magnet or electromagnet or U shaped magnet. So here we will discuss what magnetite is and we will also discuss natural magnetic, electromagnets and U shaped magnets.

Complete answer:
Magnetite is a rock mineral and it is an iron ore i.e. it has a large quantity of iron and some impurities. It is found to be attracted by magnets and it can be made permanent magnet by magnetizing it. Hence it has magnetic power i.e. it can attract small pieces of iron or small iron objects towards it. Although its magnetic strength is not that good as compared to permanent magnets. It is therefore said to be a naturally occurring magnet.
Hence magnetite are the natural magnets.

Therefore option A is the correct answer.

Additional information:
Electromagnets are magnets which are made by passing current through a solenoid.
U-shaped are magnets whose poles are made close enough to produce a magnetic field of high intensity i.e. magnetic field around the poles are much stronger as compared to bar magnet.

Note:
Magnetite can be used as a material or substance to make a U shaped magnet. That is, a U shaped magnet can be magnetite but it is not necessary that each magnetite is U shaped. Basically a bar magnet or magnetic substances are moulded to make a U shape magnet by bending it in such a way that the poles are close to each other.
