What is Electromagnetism?
The force governing 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 propagating through space at the speed of light.
What is Coulomb's Law?
Describes the force between two point charges, proportional to the product of charges and inversely proportional to the square of the distance.
What is Gauss's Law?
Relates 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.

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 there is a charge density?
It generates an electric field.
What happens when there is a current (J) and a changing electric field (∂E/∂t)?
A magnetic field is generated.
What happens when a loop of wire is placed in a changing magnetic field?
An electric current is induced in the loop.
What happens when the current in the cylinder is increased at a constant rate?
An induced electric field is generated both inside and outside the cylinder.
