Electric and Magnetic Energy

INTRODUCTION TO ELECTRIC ENERGY AND MAGNETIC ENERGY
Electric field is created by both positive charges and negative charges. Positive charges have electric field that radiate outward and negative charges have electric field that radiate inward. These fields are created by the alternating currents that produce alternating electric fields. If current passes through any electrical appliance, then a part of electric energy is converted into electric current. Electric energy is the potential energy that is associated with the conservative coulomb forces within a well-defined system of point charges.
The amount of electric energy due to the electric current is represented by the expression Understanding Electromagnetic Pulse Effects is always challenging for me but thanks to all math help websites to help me out.
E = QV = VIt = I2Rt
where V is the electric potential difference(in volts) and Q is the charge(in coulombs). Electric energy is measured in joules. Magnetic fields radiate from north poles to south poles. Magnetic energy is defined as the potential energy of a magnet of magnetic moment m in magnetic field B. It is the work of magnetic force on the re-alignment of the vector of the magnetic dipole moment. Expression of the magnetic energy is represented as
Ep,m  = - m.B

How are Electric and Magnetic Energy Related

Both the magnetic energy and the electric energy  are related by the Maxwell’s equations. Wherever electricity is present , there also exist both electric energy and magnetic energy since the invisible lines of force creates electric charges. Electric fields are resulted from the strength of the charge while the magnetic fields are resulted from the motion of charge. Strengths of both electric and magnetic fields decreases when one moves away from the source of these fields. Magnetic energy of an electric current tends to conserve the electric current. The current will decline in time only when there is electric or magnetic resistance and the magnetic energy will be lost and the electric current also decreases eventually. Electric energy plays a crucial role in lighting, computer operations, entertainment applications, cooking, space heating and so on. Magnetic generators, magnetic motors, magnetic light box etc are the devices that are intended to use renewable magnetic energy and later recycles the energy back into the environment without any pollution. Magnetic energy also supplies light, heat and water needs. It can also be used to conserve our natural resources.
