What happens when there is a changing magnetic field?
It induces an electric field (Faraday's Law).
What happens when an electric charge moves?
It creates a magnetic field.
What happens when a positive charge is present?
Electric field lines emanate from it.
What happens when a negative charge is present?
Electric field lines converge onto it.
What happens when there is a current (J) or a changing electric field (∂E/∂t)?
A magnetic field is generated.
What happens when the magnetic flux changes through a loop of wire?
An electric current is induced in the loop.
What is Electromagnetism?
The force that governs interactions between electrically charged particles.
What is an Electric Field (E)?
A region of space where an electric charge experiences a force.
What is a Magnetic Field (B)?
A region of space where a moving electric charge experiences a force.
What are Electromagnetic Waves?
Oscillating electric and magnetic fields that propagate through space at the speed of light.
What is Coulomb's Law?
Describes the force between two point charges. $F = k \frac{|q_1q_2|}{r^2}$
What is Gauss's Law?
Relates the electric flux through a closed surface to the enclosed charge.
What is Faraday's Law?
Describes how a changing magnetic field induces an electric field.
What is Ampere's Law?
Relates the magnetic field around a closed loop to the electric current flowing through the loop.
What are Maxwell's Equations?
A set of four equations that unify electricity and magnetism.
