The coil’s inductance mainly depends on the turns of the coil. So they are proportional with each other like N ∝ L The inductance value is high when the turns within the coil are high. Similarly, the inductance value is low when the turns within the coil are low. Inductor Coil Area ...
The coil has a winding wound on a rectilinear core consisting for example of a ferrite cylinder (4) trapped in a cylinder (1) of molded plastic, which has on its cylindrical outer surface a longitudinal groove in which is placed a strip (2) made of electrically resistive material and ...

Inductance is defined as the property of an electric conductor which causes an electromotive force that is generated due to a change in the current flow. There are two types of inductance: self-inductance and mutual inductance.
Calculate the self-inductance of a coil of 100 turns, if a current of 2A gives rise to magnetic flux of 50μWb through the coil. Also calculate the magentic energy stored in the medium surrounding the coil for the above value of current. View Solution Calculate the coefficient of self ...
