If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...
The geomagnetic field is generated by fluid convection in Earth’s core. How this dynamo works is complicated, and the field that the core produces is not symmetric. This has been something of a ...
Atomic physicists “are jacks of all trades,” according to Alex Sushkov. “You have to have the idea, design the experiment, build the experiment, run the experiment, fix everything, take data, analyze ...
At some point during our primary school careers, most of us probably constructed a simple compass, often by floating a magnetized needle on a cork in a cup of water. The water in such a configuration ...
Magnetic rocks with iron oxide concentrations act as natural chroniclers of Earth's past continental movements. Using small ...
Compasses were the trusted companions of sailors, explorers, and travelers for centuries, offering a simple way to find north. A small magnetized needle is set on a tiny pivot, allowing it to move and ...
Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...
