Hey buddy here is your answer::
Electromagnets are better to use rather than natural magnets. Natural magnets though they don't require any kind of electricity or some other form of energy should not be used due to some reasons.
(1) sometimes we require a strong magnetic field to be generated, using electromagnets this would be easy, by just increasing the amount of electricity. But for natural magnets this would be one constraint.
( 2) natural magnets once banged by some accident or some other reason lost their magnetic properties to some extent or completely. This is also possible when they are exposed to high heat for long time . Electromagnets are not affected by this.
(3) moreover it is not easy to handle natural magnets and can't be used easily by cranes for lifting purpose as it would create mess for dropping the lifted things and will slow down the work. By using electromagnets no such problems would be created.

Electric magnets have high electric field.
These have aligned parts. These can be modified in any desired shape.
the magnetic field of these can be controlled at any time. The magnets can get high magnetic fields varying from -ve to 0 and positive.
it is not easy to handle natural magnets and can't be used easily by cranes for lifting purpose as they will not drop.
Electromagnets don't loose their strength when heated .
Permanent magnets are not usable after time.
So electromagnets are preferred.
