The below mentioned article provides an experiment to determine the area of magnetic field of a bar magnet in a horizontal plane. The space surrounding a magnet where the force of attraction or repulsion due to that magnet is felt, is called magnetic field of that magnet. From theoretical consideration the magnetic field of a magnet is extended upto infinity. [...]
In this article we will discuss about the magnetic effect of electric current, explained with the help of a suitable diagram. When electric current flows through a conductor, a circular magnetic field is set up around the conductor along its length. This is called magnetic effect of electric current. The magnitude of the field depends on the current. If the [...]
In order to picture the magnetic field and its strength at different distances from the poles, it is convenie12341 to show the field as lines of force, generally known as magnetic lines of force. These lines have no physical existence and are only a means of representing magnetic field. Fig. 50(a) shows the magnetic lines of force of a bar [...]
