Answer 1

hey friend! here is your answer-
____________________________________________________________
A) What is an Electromagnet ?
 -------------------------------------------------------------------------------------------------
a magnet formed due to electric current is called electromagnet. an electromagnet is a coil of wire around a soft iron core which behaves
as a magnet as long as current passes through it.
it is a temporary magnet. 
 -------------------------------------------------------------------------------------------------
b) What are its uses ?
 -------------------------------------------------------------------------------------------------
electromagnet are used for-
1.they are used to transport huge masses of iron scrap.
2.small bits of iron can be pulled out from wounds.
3. they are also fitted in several devices like telephone.
electromagnet is very useful and common nowadays.
 -------------------------------------------------------------------------------------------------
c) Why steel isn't used to make an electromagnet ?
--------------------------------------------------------------------------------------------------
see according to me, steel is not used in electromagnets as steel when used will make electromagnet a permanent magnet which cannot be stopped if we stop the electric current flowing. also it will loose its properties if steel is used so that is why to make functions of electromagnet available and active steel is not used in making electromagnet.
