In the universe, magnetism has a great importance as most of the heavenly objects are influenced by the magnetic fields. The planet earth has also a constant magnetic field around it, as the magnet has a north and south poles; the earth has also the north and south poles. These poles were being in use from many years and people find their ways and directions utilizing the earth magnetic poles. Magnetic and electric fields are utilized to generate electrical power. Similarly, electric and magnetic fields are utilized to convert the electrical energy into mechanical energy by the utilization of a motor.
A field of physics is dedicated to study the electric field that is Electrostatics. Electrostatics studies the electric field in relation with the electric flux, electric potential energy, electric potential, electrostatic induction and electric dipole movement. Electric field is a vector quantity having no fixed direction and has the units of N/C (Newton per Coulombs) or V/m (Volt per meter). The field is produced due to the movement of the electrical charged particles. The movements of the charged particles produce a magnetic field. The magnetic and electric fields are such linked to each other that one influences the other. In this way, the electric fields can be described by force that a charged test particle face. The force directs the electric fields in the similar direction as that of the force (Oatley 5-27). In this perspective the idea of electromagnetism grown and referred as the field dealing with both the quantities.
Magnetic field is termed to be vector; the field has a direction and magnitude. The movement of the electrical charge produces the magnetic fields (Herlach & Miura 1-65). In this way, electrical charge or the charged particles highly influence the magnetic field. Magnetic fields are much important in determining the direction on the ship along with the most modern system like GPS (Global positioning system). Changing the magnetic
