| He'd helped plan and carry out the destruction of that warship because its existence and location were verified by a magnetometer. |
| An alkali vapour magnetometer is a highly sensitive magnetometer that works at the atomic rather than the nuclear level. |
| The technique evolved during the Second World War when the US Navy developed a magnetometer to detect submarines. |
| Even Luna 1 carried a magnetometer and found that the Moon produces no significant magnetic field, quite unlike Earth. |
| Students will build and operate a simple magnetometer using a soda bottle and a bar magnet. |
| The team hopes the magnetometer will identify the wreck site by detecting the iron used in the hulls and steam engines of the sunken ships. |
