Well, when the aluminum spool is rotating, the closeness of the aluminum to the magnets creates what's called an "eddycurrent," and this eddycurrent creates the braking effect on the spool.
当铝盘转动的时候，铝盘靠近磁片从而产生“涡电流”，这种涡电流就对线杯产生了刹车作用。

Compared with the analytical and experimental results, it is confirmed that the permanent magnet eddy-current brake is an effective braking method and FEM is suitable for analyzing it.
Resistance simulation control electricity eddycurrent system, make the revolving speed and braking moment relation accord with the condition of correspond speed and resistance relation.
