be riven a small acceleration = a theorem well understood by helicopter designers. The beams or rays mentioned do the contrary - a small mass is given a very high velocity - consequently enormous powers - greater than the total € world's power capacity - would be needed to support even the smallest object METHOD II. Direct use of Earth's Magnetic Field. : One observer (incident 65) noticed a violent motion of a hand-held “compass. if we assume from this that the objects produced a magnetic field, comparable with the Barth's field, namely 0.1 gauss, and that the observer found that the object subtended an angle © at his position, then the ampereturns of the required electromagnet is given by 0 ni = 2 oo where R is the range of the object. 0 ad 2 ct ie) hy mo in diameter, @ For instance, if R is one kilometer and the object is “10 m : ve. eee S - then ni = 1] billion ampere-~turns. Now if the object were actually only 10 meters away and were correspond= ingly smaller, namely 10 cm in diameter, it would still require 10 million ampere=-turns. These ficures are a little in excess of what can be conveniently done on the ground. They make it seem unlikely that the effect was actually observed. Now the Barth's magnetic field would react on such a magnet to produce not only a torque but also a force. This force depends not directly on the Earth's field intensity but on its irregularity or eradient. This force is obviously mimute since the change in field over a distance of ‘ f a2 n ‘4 . , _ P }, " rn 10 meters (assumed diameter of the object) is scaroely measurable = more- 4 : : : 4 , Se tee = - 4 ee 7 a ai +, over the eradient is not predictable but changes due to local ore devosits.
