Dipole moments in fish at 30MHz

[Smolley]

During my apprenticeship in 1956 I was doing some experiments associated with the fast heating of food.
Most foods responded quite well, but fish was having none of it. We had set up a 2kW @ 30MHz Radyne
dialectric heater to perform the heating function.

Water has a nuclear quadrapole resonance at about 30MHz , so it might
have worked. There was an article in Practical Electronics some time ago
exploiting this to make a magnetometer. Plastic soft drinks bottle with
a big coil round it . Inject a pulse and you got a " ba-doing" at 30MHz
which changed with orientation in the earths magnetic field.

I cooked a couple of Sea Bass in the microwave last night . Two dinner
plates front to front to keep in the water and the bits of exploding
fish.

Delicious with tartar sauce and garden peas.

Used as a metal detector. The 30MHz Quadrapole resonance is somewhere
else.
