Flashcards

Electric Field Inside a Shell

The electric field inside a conductive shell is zero, regardless of the charge distribution on the shell.

Positive Test Charge Behavior

Positive test charges move along field lines, attracted to negative charges and repelled by positive charges.

Coulomb's Law

Coulomb's Law quantifies the electrostatic force between charged objects, showing how charge and distance affect this force.

Electromagnetism

Electromagnetism is the fundamental interaction involving electric and magnetic fields. Electric forces and fields are foundational aspects of electromagnetism.
