and electric field. Yes, they are all related, and I will show you how with some water and an LED. It's a great physics demo, but I need to go over the very basic stuff first. Perhaps it's best to ...

You can even measure the gravitational field without too much difficulty. But what about electric fields? How do you measure those? It's not as simple, but there is something you can do.

It turns out the mysterious force is a previously undiscovered global electric field, a recent study found. The field is only about the strength of a watch battery — but it’s enough to thrust ...

A new study shows that the Earth’s electric field can propel these flying spiders too. The study, published Thursday in the journal Current Biology, found that when spiders are in a chamber with ...

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 ...

Scientists launched a rocket from Svalbard, Norway, that measured Earth’s ambipolar electric field for the first time. The weak field may control the shape and evolution of the upper atmosphere ...

Given their opposite electric charges, an electric field forms to "tether them together," countering gravity's incessant pull and letting some particles escape into space in the process ...

You can get in touch with Jess by emailing j.thomson@newsweek.com. A strange electric field around the Earth, long suspected to exist, has been detected for the very first time, and it is believed ...
