Is the lightning rod guiding the mine into the needle or neutralizing it in the air?
There are two kinds of lightning rod, respectively, with different principles, or lead the mine to the lightning rod after the introduction of the ground; or the positive charge is emitted, and the negative charge of the thunderstorm cloud neutralization.The former often saw the lightning rod, only a root tip, are higher than the surrounding protected objects, when thunderstorm clouds drifting across the sky, the clouds of negative charge accumulated results, there is a positive charge the same amount of savings to the lightning pinpoint, forming a distorted electric field and clouds, when the air insulation strength can not meet the requirements, air breakdown, charge clouds in rapid guide lightning tip, and then through the arrester body into the earth, so as to avoid around a range of objects being struck by lightning.A lot of needle form a circular end shape when the latter, when a thunderstorm clouds, because the charge effect of the clouds, the earth has the same polarity opposite to the rapid charge savings on the tip, and the clouds to discharge through tip charge instead of these polar and charged clouds will the clouds and savings, thus reducing the possibility of lightning.
Further, the clouds are not charged, and there are no particles of yin and Yang between the clouds and the buildings.
A lightning rod is used to attract particles in the air, which are opposite to the tip, and neutralize the other particles in the air through the point discharge to neutralize the charge in the clouds.
The clouds have charge, buildings are induced with opposite charge, strong electric field formed between the clouds and the buildings, will form a large number of ionized air particles of yin and Yang, if suddenly there will be lightning phenomenon of directional movement.
