The magnetic lines get crowded near the poles. We can observe that the magnetic field has highest intensity where the lines are most dense because the field lines will converge at the poles and diverge as we move away from it. The magnetic force will change where the magnetic field’s magnitude is changing. Where does the magnitude of magnetic force change? Similarly if we change the angle of the coil, or velocity of the particle we will see that the magnitude of magnetic force has also changed. If we change the strength of the poles then the magnitude of magnetic field will change, this will result in changing the magnitude of magnetic force as well. The strength of magnetic field has a lot of influence on the magnetic force. When any of these properties change, the value of magnetic force also changes. The factors that affect the magnitude of magnetic force are discussed in the above section. How does the magnitude of magnetic force change? The magnitude of magnetic field follows an inverse relationship with the cube of distance. The magnetic field is directly proportional to number of turns of the wire in loop and the current flowing in the coil. The factors affecting the value of magnetic field include the amount of current passing through the coil, number of turns in the coil and radius of coil. If value of any one of the factor changes then the magnitude of magnetic field will also change. In above section we discussed about the factors that affect magnetic field. It follows an inverse relationship with the radius of the coil. As we increase the radius of the coil, the magnitude of magnetic field keeps reducing.
More the current flowing more will be the intensity of the magnetic field. The magnitude of magnetic field is directly proportional to the amount of current passing through the coil.
The magnetic force depends on the intensity of the magnetic field, particle velocity, charge of moving velocity and angle between the velocity and magnetic field. when does the magnitude of magnetic force change? Vice versa happens when a varying magnetic field is passed through the coil an EMF is generated. When the alternating current passes through the coil, a magnetic field is generated between the electric poles and these poles start acting as magnetic poles. A coil comprises of a iron rod wounded with a current carrying coil. How does magnetic field arise in a coil?Īn alternating current produces magnetic field when it is passed through a coil. The places where the field intensity is more the field lines will get dense and vice versa. These lines tell us about the intensity of the magnetic field. We can represent magnetic field using magnetic field lines. We cannot see magnetic field but we can visualize it. It is a vector field which is used to describe the magnetic influence on electrical charges and materials that follow magnetism. The value of magnetic field flux depends on the strength of the individual poles. These particles experience a force that is perpendicular to their motion. Magnetic field is the measure of magnetic influence on electric charges, electric currents and materials that show magnetism.
In this article we shall answer the question- Does the magnitude of magnetic field change? Before that we shall know what factors influence the value of magnetic field.
