Explore: Magnetic Detectors

Deposits by Magnetic Measurements", published in 1879, was the first scientific treatise describing this practical use. Magnetic anomaly detectors employed

The magnetic detector or Marconi magnetic detector, sometimes called the "Maggie", was an early radio wave detector used in some of the first radio receivers

A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground

metal detectors: they can detect only magnetic (ferrous) metals, but can detect such metals at a much greater distance than conventional metal detectors, which

Integrated Circuit containing a Gilbert cell. Product detectors are typically preferred to envelope detectors by shortwave listeners and radio amateurs as they

Using magnetic instruments adapted from airborne magnetic anomaly detectors developed during World War II to detect submarines, the magnetic variations

finding sensitive detectors. In addition to its main use in crystal radios, crystal detectors were also used as radio wave detectors in scientific experiments

the steel, a powerful magnet is used. In an MFL (or Magnetic Flux Leakage) tool, a magnetic detector is placed between the poles of the magnet to detect

Chip detectors can provide an early warning of an impending engine failure and thus greatly reduce the cost of an engine overhaul. Chip Detectors consist

drills against SC-6. On 22 October, Thetis experimented with sound and magnetic detectors while G-4 lay on the bottom of Long Island Sound. Over the winter
