摘要
本文设计了一种新型电磁振子，并分析其工作原理，激光通过此装置产生两个相互垂直的简谐振动，其合成振动的图形投影在大屏幕上，具有稳定、清晰的特点。
A new type of electromagnetic vibrator was designed and constructed. Its working principle is analyzed theoretically. Two perpendicular harmonic oscillatory motions of different frequencies were produced by using laser beam exerted on this apparatus. The resultant oscillatory figures projected on a large screen is clear and stable, and the effect can be demonstrated to a large audience.
