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. What is the inventor?André-Marie Ampère
2. What is the year of experimental foundation?Circa 1820
3. What is the Ampere balance and why does it make wires wiggle?It is a device that shows how electric currents push or pull on each other. When two wires carry current, the magnetic fields they create make the wires feel a force that can be measured.
4. How does the Ampere balance measure the force between wires?It uses a movable coil or wire next to a fixed conductor. The force is balanced by known masses or a spring, letting us calculate how strong the force is.

Electrodynamics: The branch of physics dealing with the relationship between electricity and magnetism.
Lorentz Force: The force experienced by a charged particle moving in an electric and magnetic field.
Conductor: A material that allows electric current to flow through it easily.
Magnetic Field Strength: A measure of the intensity of a magnetic field at a given point.
