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. Who discovered Lorentz force?1895
2. What is the discoverer?Hendrik Lorentz
3. What is the full equation?F = q(E + v × B)
4. Why does a moving charged particle bend in a magnetic field?The magnetic part of the Lorentz force is always perpendicular to the particle’s speed and the magnetic field, so it pushes the particle sideways and makes it follow a curved path.
5. How does the Lorentz force help electric motors work?In an electric motor, moving electric charges in the motor’s wires feel the magnetic part of the Lorentz force, which pushes the wires in a way that turns the motor’s shaft.

Vector Sum: Adding quantities that have both magnitude and direction.
Cross Product: A multiplication of two vectors that results in a third vector perpendicular to both.
Classical Electrodynamics: The theory describing the behavior of electric and magnetic fields and their interactions with matter.
