Any errors, or impovements needed? Should it be in gaussian units?

N – number of turns, Fingers

What's a Fingers? I don't think I've ever see units on the number of turns.
Overall looks good, very similar to my transformer/inductor crib sheet. It could use some diagrams showing flux and such, and should include the impedance transformation characteristic (goes by turns squared) of a transformer.
Do you do crib sheets for other subjects/topics as well? My crib sheet binder gets a lot of use.

Bobbin cores and rod cores are difficult to solve, but a gapped core is not too difficult if you can guestimate the magnetic field fringent around the gap. But is the H field the same around the magnetic circuit given constant area. I'd been assuming it is in previous designs, with the results as expected, but is it true?
An inductor is an electrical component that stores energy in the form of a magnetic field. It consists of a coil of wire, often wound around a core material, and is used to control the flow of electrical current in a circuit. When current flows through the coil, a magnetic field is created, which resists changes in current flow and stores energy.
Inductors and transformers are both electromagnetic devices, meaning they use magnetic fields to function. A transformer is essentially two inductors placed in close proximity to each other. They are connected by a shared magnetic field, which allows them to transfer energy from one circuit to another without physical contact.
The most important equations in inductor and transformer design are Ohm's Law, which relates voltage, current, and resistance; Faraday's Law, which describes how a changing magnetic field induces an electric current; and Lenz's Law, which explains the direction of the induced current. Other important equations include the inductance formula, which calculates the amount of energy stored in an inductor, and the transformer equation, which relates the number of turns in the primary and secondary coils to the voltage and current in each.
The choice of materials for inductors and transformers depends on several factors, including the desired inductance, frequency of operation, and power requirements. Some common materials used in these components include copper wire, iron cores, and ferrite cores. The properties of these materials, such as their conductivity and magnetic permeability, play a crucial role in determining the performance of the inductor or transformer.
Inductors and transformers have a wide range of applications in various industries. They are often used in power supplies, electronic filters, and motors to control and regulate the flow of electricity. They are also commonly found in telecommunications equipment, such as inductors used in radio frequency filters and transformers used in telephone lines. Additionally, inductors and transformers are essential components in many electronic devices, such as computers, TVs, and mobile phones.
