Pulse induction metal detectors are one type of metal detecting technology. A pulse induction device works by sending short pulses to the coil of the metal detector. The short pulses sent to the coil create a magnetic field, which dissipates quickly at the end of each pulse. A metal target in a magnetic field will continue to be magnetized for ...

This is the set up. When the metal detector circuit is placed near to a metal object the inductance of its coil changes, and so do the frequency of oscillations. Now the two frequency will be different, there will be no cancelling and the radio produces a hissing sound. This means a metal object is detected. Simple, ha.

Metal detector circuits use an oscillator that produces alternating currents. An eddy current passes through the metal when active. Hence, the current produced passes through a coil. Doing this creates an alternating magnetic field. The magnetic field attracts the metal closets to the coil. As a result, the metal changes the magnetic field ...

When gold and surrounding soil are hit by the voltage pulse, Eddy currents in the soil dissipate faster than Eddy currents in the gold nugget. The metal detector can interpret this delay between the two signals received, enabling it to detect the metal. The rate at which this on/off pulse is emitted depends largely on the soil conditions.

A calorimeter measures the energy a particle loses as it passes through. It is usually designed to stop entirely or "absorb" most of the particles coming from a collision, forcing them to deposit all of their energy within the detector, thus measuring their full energy.
