A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

[Peter] is currently working on a new version of his pocket-sized science tricorder, and he figured visualizing magnetic fields would be cool. This led to what can only be described as a camera ...

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 ...

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, ...

Researchers at IIT Bombay discovered that magnetic fields can manipulate blood flow, potentially treating cardiovascular diseases. Their study shows that magnetic forces stabilize blood pressure, ...

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 ...

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 ...

By analyzing radio signals from India’s Chandrayaan-2 orbiter, which continues to operate efficiently and provide valuable ...
