This video presents the analytical solution for the electric field along the axis of a uniformly charged disk. Starting from Coulomb’s law, we derive the exact expression and discuss its physical ...
In this video, we derive the electric field between two charged plates using fundamental principles of electrostatics. Step-by-step reasoning, clear equations, and physical intuition are used to show ...
As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...
An international team of scientists at NASA and other institutions say they’ve discovered a weak, planet-wide electric field wrapping the Earth that was first hypothesized by researchers decades ago.
Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen and more. New experiments explore how evolution may have influenced this phenomenon.
This alternating electric field produces what are called dielectrophoretic forces, which are essentially a non-uniform electric field creating a traveling wave that pushes dust across the surface. By ...
High-speed imaging of charged droplet dynamics reveals a critical transition in the role of non-uniform AC electric fields on ...
