Question

What is the diffrenece Electromagnetism and magnetism ?

Answer 1

Magnetism is just one aspect of electromagnetism.  The electric and magnetic fields are related.  The relationship is represented by Maxwell's equations.  The magnetic field is considered to be the relativistic aspect of the electric field.  When people talk about magnetism, they are generally speaking of a static (unchanging) magnetic field.

Answer 2

Magnetism is primarily concerned with magnetic fields, but they are essentially the same field of study. Electromagnetism combines electric fields/forces with the magnetic fields/forces. If you're mathematically inclined, look up Maxwell's equations for much more detail. The cliff notes are that changing magnetic fields induce electric fields, and moving electric charges induce magnetic ones.

Answer 3

Magnetism is a characteristic of certain materials that causes them to be attracted to various metals.  

Electromagnetism is when electricity is used to induce magnetism in objects that are not typically magnetic.  An example of this is when you wrap a nail with wire, and run an electric current through the wire.  The nail becomes magnetic while the electricity is on (and might retain a little magnetism for a while after it's off).  That is electromagnetism.
