High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

Scientists have made a magnetic field discovery that could help make fusion reactors a practical reality. ... The team achieved their feat by wrapping a coil around a pellet made using special metals.

This is from the electromagnetic coil turning off and on to deliver the magnetic pulses. It’s about as loud as an MRI scan. Side Effects of Repetitive Transcranial Magnetic Stimulation ...

The turtles were put in a tank surrounded by a magnetic coil that replicated the magnetic field of the Atlantic Ocean. Every day, over two months, ...
