In this video, we derive the far-field electric field of a dipole in the perpendicular direction, explaining each step and the physical meaning behind the math. This breakdown helps clarify how dipole ...

Equipotential lines are curved lines on a map which mark out lines of identicalaltitude. The altitude pertains to electric potential or voltage. Equipotential lines are curved lines on a map which ...

The concept of the electric field being null inside of a closed conducting surface was first illustrated by Michael Faraday in 19th century who also considered as a physicist who endorsed the field ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...
