Back EMF in Inductors (Good Explanation with Visuals)

If, each time we switch on the power to charge a solenoid or inductor coil, we only leave the electric power on just long enough to fully charge the coil, and no longer, we can call this determined minimum period of time required to fully charge the coil "the most energy efficient duty cycle".
Then, when we switch the power off, the collapsing magnetic field that was stored in the coil will produce a virtually equivalent voltage & current flowing in the opposite direction. Now, how can we make use of this phenomena to gain work ???
Here are some clues :
Electrical Plasma Energy Character from High Voltages
When the 1st scientists determined the total amount of heat that could be generated by one watt of electricity passing through a resistor (3.413 Btu / watt) they didn't use an extremely high voltage & low amperage current that has plasma energy physics character which can break atomic & molecular bonds & even cause transmutation of elements.
This new area of science has a lot yet to be characterized, although has already proven to produce much more efficient heaters, metal melting systems & water to gas systems.

Like compressing a spring or cocking a bow to shoot an arrow, it may take longer to charge the inductor coil, but the release of the energy stored in the inductor is typically released much faster, and comes out with a much smaller amperage, yet with a much greater voltage pressure.
This higher voltage pressure can be employed to do work in many applications that can not be done with smaller voltage pressures. We can compare this method of rapidly pulsing high voltage electricity to do work with that of Karate Chop Physics !
A given pressure distributed over a long period of time can only do so much work. But that same total pressure delivered in a much shorter period of time can break wooden boards or molecular bonds & penetrate much deeper into materials than could be done otherwise. We haven't created any more energy to do the work, we just utilized that energy in a much more conservative and efficient way.
If we use this much higher voltage pressure released from an inductor coil to penetrate deeper or longer into a electrically resistive heating wire or other materials, that higher voltage pressure will allow the electricity to conduct much further down the resistive wire, or much further & deeper into most all other materials than that which could be done with a lower voltage power supply of equal total expended energy.
Increasing the Switching Speed
The PWM feedback loop adjusts the output voltage by changing the ON time of the switching element in the converter. A PWM can be made to produce a series of square wave pulses which provides a DC output voltage that is equal to the peak pulse amplitude multiplied times the duty cycle. The duty cycle is defined as the switch ON time divided by the total period. This relationship explains how the output voltage can be directly controlled by changing the ON time of the switch.
When a voltage is applied to an inductor, a current is made to flow through its conductors creating an expanding magnetic field (flux). This expanding field induces a current (counter EMF) possessing an opposite polarity from that of the applied voltage. The amount of this counter EMF is directly related to the derivative of the applied current, i.e., the faster the rise & fall time, the greater the current of the counter EMF.
Doubling the Conductor Mass Doubles the Power
A solenoid or an inductor will produce a magnetic field intensity which is determined by the length of the coil, the number of turns of wire & the applied current. If you double the turns (mass) of the wire, you will double the resultant magnetic field strength without using any more electrical energy, except for an insignificant amount of wire resistance loss. So, for a solenoid or inductor which employs the working energy of an extremely fast collapsing magnetic field (back EMF), a doubling or more of the conductor mass is a sure easy way to gain extra working energy without the added cost of consuming more electrical energy.
By increasing the voltage pressure, you can proportionately reduce the amperage, and be assured that this smaller current will easily make it completely through the entire length of the coil wire.
