. The Earth beneath the sea : History . Fig. 3. Proton magnetometer for towing behind a ship. 550 cm3 and is surrounded by a coil having 4220 turns of copper wire mm in diameter. The fish is a cylindrical container with fins to render it stable. It is made of fibre-glass impregnated with an epoxy resin and is 25 cm long and 10 cm in external diameter. A current of 1 amp through the coil gives a polarizing field of 320 gauss. The fibre-glass fish contains only the bottle and the coil. It is joined by a 3-m length of screened cable to a second fish which contains the pre-amplifier and the re
