electric field magnetic field relationship

The above figure shows the electric field of a positive point charge. The electric field is directed away from the charge and potential is positive at any finite distance from the charge. If we move away from the charge, i.e., in the direction of..

When a long wire is coiled in the shape of a spring so that the turns are closely spaced and insulated from each other it forms a solenoid. Generally, a wire is coiled over a non-conducting hollow cylindrical tube. An iron rod is often inserted inside the hollow tube. This rod is called the core. h..

The rod AB gets displaced. The rod AB is connected in series to a battery, a key and a rheostat Switch on the current Procedure Observation Repeat the experiment by changing the direction of flow of current. The rod AB gets displaced in the reverse direction. ..

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 settles tangent to the field lines shown. The magnet..

Magnetic Field - Magnetic field is a region near a magnetised body where magnetic forces can be detected. In a magnetic field, the magnetic dipole (Two equal and oppositely magnetised poles separated by a distance is re..

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..

Electric Field - The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the e..

The electric field or electric field strength is the electrostatic force acting on a small positive test charge placed at that point. If is the electrostatic force experienced by a test charge q at a point, then the electric field intensit..

The direction of magnetic field around a current carrying conductor can be determined by using one of the laws given here. Rule Pictorial Representation Right Hand Thumb Rule Imagine that you are holding the conductor in your right hand with the fingers curled ar..
