vector force fields

Electric Field Lines - 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..

Crystal Field Theory - 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 ..

A pictorial representation that gives the direction of the magnetic field at various points in a magnetic field is called a map of the magnetic field..

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 other. These field lines..

Electric field produced by a dipole is known as dipole field. Let +q and -q be equal and opposite point charges separated by a small distance 2l. The strength of an electric dipole is measured by a vector quantity known as electric dipole moment known as electric dipo..

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..

4) For charges of opposite sign the force acts in a direction opposite to that of positive charg..

>These points form a curve The curved line represents a magnetic field line or magnetic line of force Repeat the above procedure and draw as many lines as you c..

Magnetic lines of force form closed continuous curves. Outside the body of the magnet, their direction is from north to south pole. The tangent to these lines at any point gives the direction of the magnetic field at that point. No two lines can intersect each other. ..
