A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...

The current induced in the ring has an inductive phase shift relative to the induced EMF, and this phase-shifted current feels a Lorentz force from a radial magnetic field from the electromagnet's ...

Get Instant Summarized Text (Gist) The study investigated the melting temperature and phase stability of iron under conditions similar to Earth's core using ultrafast X-ray absorption spectroscopy ...
