You can study the
phenomenon of self-induction of a coil in the following visual , where you will be able to see how it depends on
some of the properties of the circuit, as the law of Henry states:
emf is the self-induced electromotive
force, dI/dt is the variation of the intensity of current with time and
L is the self-inductance or inductance of the coil, which is a property
of the coil and is measured in henries. Its value is equal to:
where μ is the magnetic
permeability of the medium, n is the number of loops and l is the
lenght of the coil. |
