[Tom] doesn’t much like breadboarding. He prefers to wire up prototypes with perfboard and solder point-to-point with enameled magnet wire. That may sound troublesome to some of you, but [Tom ...

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions ...

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 ...

An older medium of magnetic recording now superseded by magnetic tape. The magnetisable wire recorder was the first means of field recording and was used as early as 1899. The Danish engineer Valdemar ...

Merging some esoteric physics principles with an advanced instrument creates a magnetic microscope with resolution better ...

Uncoated tape used to separate other sections of tape is called leader. Magnetic tape superseded the earlier magnetic wire recorders after World War II because of the ease with which one could splice ...

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.
