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.
A magnetic field changes the direction of a moving charged particle, but it doesn't do work.
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.
Ampère's law relates the magnetic field of a closed loop to the electric current passing through that loop.
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.
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.
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.
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.
Describes the three forms of magnetic levitation: using superconductors, movement, or alternating current.
The ability of a circuit to fight the electric flux that is produced by the circuit itself.
