Exploding Hot Dog

Exploding Hot Dog

This is a hot dog/sausage/wiener about to be cooked from inside out. Apply 3 kJ from a pulse capacitor charged to 6 kV and the iron wire vaporises with many thousands of amps. The explosive energy is discharged in less than a millisecond.

Measuring magnetic field strength

Using direct force on an electromagnet for measuring magnetic field strength.
Measuring magnetic field strength by direct force measurements

Here is my attempt at measuring magnetic field strength. To measure the field generated by the electromagnet above I made a coil that could be placed in the magnetic field.

Spot Welder AC

This AC spot welder uses a low voltage with very high current.

I made this as I thought I may need something to make joins for use in a vacuum that may get red hot. Epoxy and plain or silver soldering would not do. It uses a 6 V 90 A transformer and is able to spot weld a variety of mostly thin metal sheets.
