It’s thus worth putting in the effort to make a better antenna, and if you’re not fortunate enough to have a lot of space, your best choice may be a magnetic loop. [Robert Hart] takes us ...

After searching the web for such a project and trying many of them, he decided to build his own detector based on an induction loop. As you may have guessed, this kind of detector works by ...

The external magnetic field modulates the inductance of the loop, which is detected by monitoring the resonant ... The high sensitivity of SQUIDs allows for the detection of deep and subtle magnetic ...
