Martin told me she would army crawl up to the turtles on the sand and dab around their eyes with a foam swab, soaking up the ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

Gravitational forces that make things fall down to the ground – unless another force stops them. An apple falling from a tree falls straight down. A ball thrown up, comes back down. And so do we ...

It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and sizes. Bar magnets and horseshoe magnets ...
