The principle states that when a number of charges are interacting , the resultant force on a particular charge is given by the vector sum of the forces produced by the individual charges. If several point charges q 1 , q 2 , q 3 .............. q n simultaneously..

A current carrying conductor experiences a force when placed in a magnetic field. The direction of force is reversed when the direction of current in the conductor is reversed. The force acting on the current-carrying conductor can be changed by changing th..

1) Both magnetic and electric field depend inversely on the distance between the source and the field point 2) Both are long-range forces 3) Principle of superposition applies to both fields as the fields are linearly related to the source..

Multiple Charges - Coulomb's law describes only the interaction of two point charges. Experiments show that when two charges exert forces simultaneously on a third charge, the total force acting on that charge is the vector sum of the forces that the two char..

The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved and remains unchanged due to reaction forces between the forces of the syste..

Magnetic Field Lines - The compass needle always lies along the direction of the field. The figure below shows the lines or pattern of the field, when the compass needle is placed at several places. These lines do not really, tell us the effect that magnet has on the o..

The generator is an application of electromagnetic induction. It works on the principle that when a wire is moved in a magnetic field, then the current is induced in the coil. A rectangular coil is made to rotate rapidly in the magnetic field between the poles of a horse shoe ty..

The magnetic field induction at a point is said to be one tesla if a charge of 1 coulomb while moving at right angles to a magnetic field with a velocity of 1m/sec experiences a force of 1N at that poin..
