Magnetic Field Energy pending

Self-inductance; RL circuit The ability of a circuit to fight the electric flux that is produced by the circuit itself.

Levitation Describes the three forms of magnetic levitation: using superconductors, movement, or alternating current.

Aurora Borealis The Auroras are a result of these electrons and protons from the solar wind colliding with the our atmosphere. This causes a breathtaking display of light near the Earth's poles.

Maxwell’s addition to Ampère’s law Maxwell suggested that we add a term to Ampere's law, which contains the derivative of the electric flux. This is called the displacement current.

Motional EMF; AC Motors To create an induced EMF, and must change the change in the magnetic flux by either changing the magnetic field in time; changing the area in time, or changing the angle θ in time.

Electromagnetic induction; Faraday’s law A current, therefore an electric field, can be produced by a changing magnetic field. This current wants to oppose the change in the magnetic field.

Ampère’s law Ampère's law relates the magnetic field of a closed loop to the electric current passing through that loop.

Biot-Savart law; Gauss’s law for magnetism The Biot-Savart law describing the magnetic field generated by a constant electric current. Gauss's law for magnetism says that magnetic monopoles do not exist.

Moving charge; Cyclotron A magnetic field changes the direction of a moving charged particle, but it doesn't do work.

Magnets; Charges in motion; Lorenz force The magnetic force acting on a moving charge can be expressed in terms of a magnetic field. Similar to how the electric force can be expressed in terms of an electric field.
