Magnetic Field
A magnetic field is defined as a region in which a magnetic force is present. In a magnetic field, the magnetic dipole (two equal and oppositely charged or magnetized poles separated by a distance) experiences a turning force, wh..
Magnetic Fields and Field Lines
Magnetic Fields and Field Lines - If a small compass needle is placed at a point near the north pole of a bar magnet, the needle turns round on its pivot and settles in a fixed direction as shown in figure. At other points away from the pole the needle settle..

These lines do not really, tell us the effect that magnet has on the other. These fieldh..Neutral Points in a Magnetic Field
As a result of two magnetic fields acting at the same place, the resultant field has a special feature. At a particular point, if the compass needle does not point in any particular direction, then there is no net magnetic field at the point. ..
Features of Earth's Magnetic Field
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 towa..
Evaluation of Magnetic Field
Consider a straight conductor XY carrying a current I as shown. To find the magnetic field at P, consider a small current element of length d..
Magnetic Field due to Toroidal Solenoids
Toroid is a hollow circular ring (like a medu vadai) on which a large number of turns of a wire are wound. The above figure represents a toroid wound with a wire carrying a current I. Consider path 1, by symmetry , if there is any field at all in this region, it will be tangent to the pat..
