are force fields possible

Lorentz Force - The force experienced by a charged particle moving in space where both electric and magnetic field exist is called lorentz force. The lorentz force is therefore the vector sum of force due to electric field and th..

The gravitational field intensity at a point is defined as the force experienced by a unit mass placed at that poin..

Michael Faraday (1791 - 1867) introduced the idea of lines of forces. They are nothing but a way of pictorially mapping the electric field around a configuration of charges. It is the curve drawn in such a way that the tangent to it at each point is in the direction of the net h..

Bonding in a complex ion is due to electrostatic interactions between the positively charged nucleus of the central metal ion and electrons in the ligands i.e., attractive as well as repulsive interactions. (i) The attractive forces will arrive due to the positive metal ion and the negati..

They are nothing but a way of pictorially mapping the electric field around a configuration of charges. It is the curve drawn in such a way that the tangent to it at each point is in the direction of the net field at the point. An arrow on the lines of force is a..

Calculations of electric field intensity are of tremendous importance due to the technological applications of electric forces. To determine the trajectories of electrons in a T.V. tube, in an accelerator used in cancer radiotherapy, or of charged particles in a semiconductor el..

Conclusion - Principle of electrostatics and electromagnetism play a very vital role in all modern scientific developments. Coulomb's law may be regarded as merely a special case of Gauss' law or we can say Gauss's law is generated form of Coulomb's law. Gauss' law makes it possible to ca..

The earth's magnetic field has an axis which is inclined 20 o west of the axis of rotation of earth. The point where this huge earth's magnet cuts the earth's surface are the magnetic poles. A freely suspended magnet has its north pole pointing towards geographic north; we therefore desig..

A solenoid is a long coil (shaped like a cylinder) containing a large number of close turns of insulated copper wire. The figure above shows a solenoid SN whose ends are connected to a battery B through a switch X. When a current is passed through a solenoid, it produces a magnetic field..

where E r is the component of electric field along the direction of 'r'. dv/dr is called the potential gradient and the negative sign implies that electric field acts in a direction of decrease of potential. The above expression also indicates that E is not necessa..
