Gerakan relatif untuk menghasilkan arus teraruh
Relative motion to produce induce currents

Mekanisme penghasilan arus teraruh atau d.g.e teraruh:
Mechanism of the production of induced current or induced e.m.f.:

Apabila gerakan relatif antara konduktor dan magnet dilakukan, konduktor akan memotong garis medan magnet dan mengubah
fluks magnet. / Whenever there is a relative motion between a conductor and a magnet, the conductor cuts across the magnetic lines of
force and changes the magnetic flux.
