Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Inductance?Essential for resonant circuits, filters, and power converters in electronic systems
2. What is the mathematical formulation?Described by Maxwell's equations, unifying electricity and magnetism
3. What is inductance and why does it matter?Inductance is a property that lets a coil of wire store energy in a magnetic field when current flows. It helps control how electricity moves in circuits.
4. How does a coil of wire create a magnetic field?When current goes through the coil, it makes a magnetic flux that goes through the core. The more turns or a bigger core, the stronger the field.

Magnetic Flux: The measure of the total magnetic field passing through a given area.
Back Electromotive Force (Back EMF): An induced voltage that opposes the applied voltage, characteristic of inductors.
Permeability: A measure of a material's ability to support the formation of a magnetic field within itself.
