What is Megnetic Fields? Explain.

a magnet has a space around it where magnetic materials feel a force. we say that there is a magnetic field around the magnet. magnetic fields can be studied using a plotting compass. The compass needle is a small magnet which can turn on a pivot. In a magnetic field , its north pole is pulled one way and its south pole is pulled the other. the needle always comes to rest in line with the magnetic field.
