2 Theoretical basis of an all-optical atomic magnetometer The atomic magnetometer reflects the magnitude of the magnetic field by measuring the Larmor precession frequency of the polarization vector ...

(e.g Permanent magnets that are in motion; this motion can cause a change in the magnetic field.) If the current is constant and the electromagnet is stationary. (e.g. Electromagnets are created by ...

Charged particles will only experience a force in a magnetic field if they are moving ... Magnetic force on a current carrying wire A wire carrying current is essentially a stream of charged particles ...

This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and more.

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.

Scientists have discovered a new reason for turtles to dance for joy: Loggerhead sea turtles seem able to discern and remember magnetic field signatures, which could help them find food.

A new trick for illuminating the internal ordering within a special type of magnet could help engineers build better ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells the ...

An international team of scientists has modeled the formation and evolution of the strongest magnetic fields in the universe.

An international team of scientists have modelled formation and evolution of strongest magnetic fields in the Universe.

“The current behavior of magnetic north is something that we have never observed before,” William Brown, a global geomagnetic field modeler at the British Geological Survey, says in a statemen ...
