While these animations seem good, the wording and descriptions are awful and will make you more stupid than not ever hearing them because they give people the wrong ideas of the fundamental basics. Consider that the inductor is never really something that would be "Happy" and doesn't "want to" slow mangnetic inductance. I only came here to say this because it's one of those things that it essential to understanding the physical universe. There are only three basic components in any modeled system. Inductors, Capacitors, and Resistors. You can go further and put decision elements in there as a fourth, but those are not necessarily "physics" based components. Inductance is a measurement of the rate of change of current when acted on by an unbalanced voltage. Note that an object's mass is another version of this. Mass is a measurement of the rate of change velocity (i.e. acceleration) when acted on by an unbalance force. They used voltage and force synonymously in this video without the proper connection (once they called what is actually a magnetic field direction and another time were analogous to voltage). Essentially, an inductor component is a DYNAMIC Energy Storage Device. Note the similarities to a capacitor and a spring. A capacitor component is a STATIC Energy Storage Device. An Energy DISSIPATIVE component is like an electronic resistor, or physical friction where the dynamic or static energy is transformed into HEAT. The fourth type of device people often use is wound up in some kind of decision, such as a switch, or any other type of "lever" or some kind of remote command. The term often used is "Operational Amplifiers" but they can be simpler or even more complicated than what that term defines. Anything with logic or a switch in it would be a decision based device. If one understands the three "physical" device analogies (plus the fourth one), you can model ANYTHING. Even buying patterns, human behavior, system dynamics (i.e. Newtonian physics), analog electronics, heat transfer systems (thermal mass would be a capacitive component in this case), financial systems, learning systems, flow in pipes (i.e. pumps are like batteries), chemical systems, etc. It gets even more interesting when you apply statistics to it, but while they can be combined statistical modeling is of a different nature than using the four components. Often we apply the four types plus statistics when modeling "mixing" or "kinetic" type problems (like Brownian motion). Another example of a mixture of these styles is quantum mechanics (consider the cat is both alive and dead because the chances are 50%). Once verified though, the statistics are no longer part of it. Hopefully this summary here was helpful and shored up the descriptive (not visual) deficiencies of this video..
