Many magnetic sensors are used in our lives, such as computer hard drives, compasses, household appliances and so on. What are the classifications of current sensors? According to different measurement principles, current sensors can be mainly divided into: shunts, electromagnetic current transformers,...

The shape, determined by side lengths and angles, affects the triangle's symmetry, area calculation, and structural applications. 2 What is the sum of the angles in a square? The sum of the angles in a square is 360 degrees. 1 Share Your Discovery Share via Social Media Embed This Conten...
They said that if the geomagnetic field faded or reversed, our compasses would not work, and GPS would not work either. Sunspots are holes where the sun dimples down, and a solar flare is where material rushes out of this central bore (the body of the black spot) like a geyser! The ...
The force due to the cross product of the moving ions in the atmosphere, by the Earth's magnetic field, will tend to move free electrons and negative ions downwards while it lifts positive ions. That will tend to sort the charges and is consistent with the polarity of the Earth electric...
