This presentation uses a free template provided by FPPT.com Electric field Electric field is present due to the deficiency and efficiency of the electrons. The presence of charge crates the field within which the impact can be observed by the other charged body The interaction of two field of charges generates the electric force

This presentation uses a free template provided by FPPT.com Elctric lines of force Electric lines of force of positive charge are away from charge, and towards the charge for –ve charge.

This presentation uses a free template provided by FPPT.com Magnetic field magnetic field is the effect that is produced due to the changing electric field. Magnetic field is present from atomic or sub-atomic level to the whole universe in the form of poles.

This presentation uses a free template provided by FPPT.com Bar magnet Ends of the bar magnets are called poles like poles repel and unlike attract All the magnets have the north and south poles regardless of the shape. Field lines are directed from north to south.

This presentation uses a free template provided by FPPT.com Lorentz Transformation of fields Electric and magnetic fields are the two aspects of the field of electromagnetic force. The charge at rest has just electric filed there is no electric current associated with it,no magnetic field As the charges is moving with some velocity no there is other kind of electric field there is current and magnetic filed is no more zero now. Transformation of the electric and magnetic field is not like the space and time,but behave in the same way as angular momentum and boost vector.

This presentation uses a free template provided by FPPT.com Interpretation of the transformation If the objects have well defiend transformation properties then these are geometric objects. Electromagnetic field has the six- dimensional objects in space and time. LORENTZ transformation properties are defined by both E and B not by alone.both collectively define the transformation.

This presentation uses a free template provided by FPPT.com Gauge theory Classical electromagnetism is the first example of gauge symmetry. The for determination of E or V,any one of these must be completely defined. Without the electrostatic knowledge of one other can not be determined If the potentials have the constant difference then they indicate the electric field. That is due to reason electric field corresponds to variation in the potential from one point in space to another, and the constant C would cancel out when subtracting to find the change in potential.

This presentation uses a free template provided by FPPT.com Gauge transformation  A Is the vector potential.  f is dependent on the position and time and this is the function that can be differentiated twice.  there is no variation in the fields under the gauge transformation, and therefore Maxwell's equation are still satisfied.  That’s why, Maxwell's equations have a gauge symmetry.
