A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their ...

Would a dramatic change in the Earth's magnetic field affect creatures that rely on it during migration? Late on a January night in 1993 I found myself on a beach on the Pacific coast of Costa ...

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

Materials are known to interact with electromagnetic fields in different ways, which reflect their structures and underlying ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

A permanent magnet is always magnetic. 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 ...

Now they increasingly believe the turtles are also able to plot a magnetic map ... in a tank surrounded by a magnetic coil that replicated the magnetic field of the Atlantic Ocean.
