How can you “see” the electric field strength lines?
August 25, 2020 | Education|
Tension lines are just a technique for graphing fields. They help to visualize the picture of the field in space. However, they can be made “visible”. We put small grass seeds (or semolina) into a cuvette with a transparent viscous liquid, such as castor oil or glycerin. The seeds are randomly distributed over the surface of the liquid. We will place charged bodies there – two oppositely charged balls. Near these bodies, the seeds line up in chains along the field strength lines.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
