I have been trying to learn about the importance of inductance in circuits. I believe that a person could create a solenoid and when current is applied, it produces a back EMF. To me, it seems as though it is acting like a resistor, or maybe even a way to store energy in a field.
But, in the event that one wants to create a solenoid for a door bell, lock, or whatever....what does inductance mean? In these situations, it seems as though a larger magnetic field would produce a stronger solenoid, and a larger inductance. Is this ok? Does this mean the circuitry that is driving the current to the solenoid needs protection from a larger back EMF? Should a person designing such things try to minimize inductance by altering the dimensions of the solenoid?
Seems pretty confusing, but the ratio of the diameter to the length seems to produce a predictable inductance number....but what this means in the practice of design, I have no clue.
