C31-1 A source of emf which produces time-varying current for example an alternator, or solenoid, and current loops rotating in a magnetic field of a permanent magnet, ferromagnetic material.
C31-1 This is commonly used for electrical power transmission because of the lower electrical power dissipation associated with $i^2 R$ for high-voltage step-up that can be provided by electrical transformers on a time-varying electrical current.
