Abstract
A self-leveling laser alignment tool and method thereof which provides a laser beam in a substantially truly level or plumb orientation are disclosed. Magnetic attraction is used to compensate for leveling errors of an approximately or partially leveled pendulum platform that is suspended from a flexible suspension element having a predetermined material stiffness. The material stiffness of the suspension element is compensated by using a magnet which pulls the pendulum platform into an orientation that is substantially truly level and plumb.
