It’s a riot of brass and steel, with a hand crank that drives the main winding shaft while powering a cam that guides the wire along the long axis of the coil form. Cams can be changed out for ...

Instead of using an electrode, Saha and her team turned to magnetic coils of wire. Over two centuries ago, physicist Michael Faraday described how electric current running through a coil of wire ...

Even with the kinds of coils used in chokes and transformers ... The idea is to pass a small spool of magnet wire through the toroid’s core while simultaneously rotating the toroid to spread ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

I went magnet fishing and I had an unbelievable day! Crazy day of magnet fishing! I used a giant magnet and found a bunch of coils of wire in the water! It is wild there is so much stuff to be found ...
