Imagine that you have a constant electric field near some object. You want to move an electron from point A to B as shown below. Illustration: Rhett Allain.

You assumed that the electric field is constant outside of a battery. It isn't. Producer: Yes, but this gets across the idea that sharks are very sensitive to electric fields.

A new study is shedding light on why solar radiation is more effective than other forms of energy at causing water to ...

Nature - Vortex rings in a constant electric field. Ions in solution screen out the electric field for biases below 2.4 V. Sustained upward forces occur only at higher biases for which hydrolysis ...

The team then upped the stakes by changing the electric fields from constant static to a pulse, which mimics what sea creatures produce. They pulsed electric fields 25, five, and finally one time ...

For a hydrogen atom, the upward pull of this electric field is 10.6 times stronger than gravity pulling downward, said Alex Glocer, a NASA physicist and co-author of the study. Advertisement ...

But electric fields are a dynamic phenomenon, explains Hunting. “Flowers typically have a negative potential and bees have a positive potential,” Hunting says. “Once bees approach, they can ...

And these electric fields of flowers can change when it has been visited by a bee, and other bees can use that information to see whether a flower has been visited.

Scientists found that dolphins have an ability to sense electric fields, which may help them hunt and navigate the seas. By Carolyn Wilke Newborn bottlenose dolphins sport a row of hairs along the ...
