It is a branch of science which shows the behaviour of the electrically charged particles in the presence of the magnetic field. Here electromagnets is small wire through which electricity is passed to generate the magnetic field. These electromagnets are used to strengthen the magnetic field which are majorly used for the industrial purposes, consumer products, research field etc.
Electromagnetism includes various topics like the polarisation. diffraction and transmission of electromagnetic waves, distribution of charge in the matter, motion of charge etc. Based on the above principles different types of conductors, insulators are constructed.
