simply states that the magnetic field strength H is always parallel to the magnetic induction B, but that it has always the absolute value HT, independently of the value of B. From this ...

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 magnetic field is caused by the current flowing in the wire. The bigger the current the stronger the magnetic field and hence the stronger the electromagnet. Hazard Consequence Control ...

In the new study, the researchers found that this magnetic field would be incredibly weak — roughly a billionth the strength ...

The largest magnetic fields in the universe may have found themselves charged up when the first stars began to shine, ...
