This undated handout photo received from National Geographic Pristine Seas on January 28, 2025 shows a green sea turtle hatchling swimming for the first time in the lagoon of Bikar Atoll in the ...

A magnet small enough to fit in the palm of your hand can match the strength of some of the world’s most powerful magnets for the first time. But superconducting magnets that produce strong magnetic ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap off-the-shelf ...

Samsung’s Galaxy S26 series may not have built-in magnets, but that hasn’t stopped the company from going all-in on magnetic accessories. The latest is a neat little magnetic case for Galaxy Buds 4.

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own planet, not even making it through the thin crust. Roughly 3,000 ...

An electrical current running through a wire generates a surrounding magnetic field which is detectable by a compass. The right-hand is used to determine, at each position, the direction of this ...

Using a magnetic compass to calculate the current in a wire. Learn how magnetic fields, compass deflection, and basic electromagnetism principles connect in a practical physics experiment.
