A quick introduction to the property of inductance, and more specifically, self inductance. Its important to note that inductance is basically a circuit fighting the changes a magnetic flux is introducing. Self inductance is also based on the geometry of a circuit rather than just a mathematical function. This is why physicists utilize shapes like solenoids when conducting certain magnetic experiments. Self inductance is mathematically thought of as the ration between the magnetic flux and the flow of the current in the closed circuit. This topic will be very useful in the next video where well cover another kind of circuit that involves inductance.
Self inductance is the ability of a circuit to oppose the magnetic flux that is produced by the circuit itself.
Running a changing current through a circuit creates a changing magnetic field, which creates an induced emf that fights the change.
The symbol for self inductance is L. The units of inductance are henrys, where one henry is one volt*second per ampere.
Self inductance is purely a function of the circuit’s geometry.
