Anti-parallel currents refer to two electrical currents flowing in opposite directions. They create magnetic fields that repel each other.
Magnetic field lines are visual representations of the direction and strength of a magnetic field. They show how a compass needle would align at different points in space.
Ampere's Law states that the magnetic field around a closed loop is directly proportional to the current passing through it.
Lorentz Force: Lorentz Force describes the interaction between a charged particle and an electromagnetic field.
