How early this property was found, or how, we do not know. The name electricity is derived from elektron, the Greek name for amber. The early Chinese and Persians knew of the lodestone, and of the magnetic properties of amber after it has been rubbed briskly. The Romans were familiar with these and other electrical effects.
Where there is a rock, or some peculiar conformation of the ground to attract attention, men and beasts will head for it, attracted somewhat after the fashion of a compass-needle by a lodestone or lump of iron.

Raffles was waiting for him in the stables, and he was very friendly and familiar, which always annoyed Jack immensely. "Glad you're in time, sir, and to 'ear the dibs a-rattlin' in your pockets."
Moreover, in 1576, Norman, a compass maker in London, showed that the north- seeking end of the needle dipped below the horizontal.
