      Allow me to ask, why is the current in the circuit changing over time? I thought this is series circuit in which current is constant?

      @@marq6325 the current wants to go from zero to some max value. In a simple resistor circuit it happens almost instantaneously but when an inductor is introduced it forces the battery to increase the current slowly in some equilibrium condition. Once the current reaches its maximum value then the circuit behaves like a normal resistive circuit except that the inductor stores some energy in magnetic field.

      Initially current inside insulator is zero so is the magnetic but when current increases, because of the shape of inductor, the magnetic field increases too.

    i always find it fun, when teachers explain pure science by saying "the coil hates the change in current" or f.ex. "the electrons WANT to have 8 electrons on the outer shell". ofc its easier to understand it like that but for people who are driven by pure facts and rationality its controversive when they explain it like that and its fun

    *_Summary Of The Video :-_*
    *Inductors and Self Inductance*
    * When we connect a bulb to an inductive circuit using a DC supply , we notice that bulb takes some time to glow in its maximum brightness.
    * Inductors do not have any problem with current.
    Inductors have problem with *_change in current_.*
    * Whenever there is change in current across an inductor , it induces an *EMF* to oppose that change in current.
    * The ability of an Inductor to oppose the changing current by inducing an EMF is often called *INDUCTANCE* (Self Inductance)
    * If changing current and opposition both are happening in the same coil then it is called *SELF INDUCTANCE*
    * Inductance is like *Inertia* .
    * Unit Of Inductance - *Henry*
    * When we turn off the switch we see a *Spark* because of incredibly high voltage supplied by inductor due to decreasing current.
    * It is dangerous to turn off switch of an inductive circuit because we might get a heavy shock.
