Metals do not like magnetic fields or current so it creates the resistance with the falling magnet out there. This resistance slows down the movement of the magnet. This phenomenon is bitterly known as Lenz’s law. Due to the slowdown of the progress of the magnet it does creates lesser electric field as the metal wants it to be due to its non magnetic nature, in the mean time the gravitational power of earth which is as the result of the presence of big magnet inside crust of earth’s surface continues to attract the magnet and then the speed rises and subsequently the speed slows down due to regeneration of electricity inside copper wires still the magnet reaches to its normal speed when it drops to the bowl which is at the outside of the copper pipe.
When magnetic storm appears the normal angular shift of one by two degree changes up to five degree and this could go on for some hours. That is why you will need to record and measure these angular shifts below of one by two that is of one by four as at some distance the power of magnetic shift is weaker and at some distance the power could be higher and it is better to check for one by fourth of distance and with this manner the performance and the movement of solar surge could be well recorded and the amount of time this magnetic shift occurs could be well known. With this, you could measure to bad weather most preferably effected through solar surges and the Earth’s environment in calculating such bad weather.
