I. Speed of the magnet: The faster the magnet moves inside the coil, the greater the emf induced in the coil.
II. Strength of the magnetic field: The stronger the magnetic field, the greater the emf induced in the coil.
III. Number of turns in the coil: The greater the number of turns in the coil, the greater the emf induced in the coil.
