| + | ====== 2. Electrical damping ====== | ||
| + | A magnet suspended by a spring will display simple harmonic motion when displaced. lf the magnetoscillates within a coil connected to a resistor, its motion will be damped. nvestigate the factors thataffect the damping. | ||
| + | ====== 2. 电磁阻尼 ====== | ||
| + | 一个由弹簧悬挂的磁铁在位移时会表现出简谐运动。如果磁铁在连接有电阻的线圈内振动，其运动将会受到阻尼。研究影响阻尼的因素。 | ||
