The average Hackaday reader likely knows, at least in the academic sense, what a magnetic ... what the field lines would look like on its electronic paper display. Relative field strength is ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

To investigate, describe and recall how the strength of the magnetic field depends on the current in the coil, the number of turns in the coil and the material used as the core of the coil.

The Hall switch JZ8002C/0.5m, which functions as an active magnetic-electrical conversion device, is indispensable in various sectors, including light manufacturing and printing. This article ...

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 ...
