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 early quantification?Coulomb's Law quantified electrostatic forces between charges
2. What is the key experimentalist?Michael Faraday discovered electromagnetic induction
3. What did the Greeks discover about electricity and magnetism?They noticed that rubbing amber could attract objects and that a special stone called lodestone could pull iron. These early clues showed that electricity and magnetism existed.
4. How did scientists start measuring electric forces?In the 1700s, Charles‑Augustin de Coulomb used a special balance to measure how strong electric charges pull on each other, creating Coulomb’s Law.

Electric Field: A region around an electric charge where other charges experience a force.
Magnetic Field: A region around a magnet or moving electric charge where magnetic forces are exerted.
Electromagnetic Induction: The production of an electromotive force across an electrical conductor in a changing magnetic field.
Electromagnetic Waves: Ripples in the electromagnetic field that propagate through space, carrying energy.
