The basic design of a search coil magnetometer consists of many thousands of turns of wire wound on a high permeability core. When a time-varying magnetic field passes through the coil, a time-varying voltage is induced due to Faraday's law of magnetic induction.What is a vibrating-sample magnetometer?
Vibrating-sample magnetometers (VSMs) detect the dipole moment of a sample by mechanically vibrating the sample inside of an inductive pickup coil or inside of a SQUID coil. Induced current or changing flux in the coil is measured.What is the sensitivity of a small coil magnetometer?
Sensitivity of the small coil magnetometer depends on the size and number of turns. This is used to detect only variations in the field (due to motion or due to the AC nature of the field). Since usually B needs to be measured instead of dB/dt, an integrator is usually used to obtain signal proportional to magnetic field B.What is a a magnetometer?
A magnetometer is a device that measures magnetism—the direction, strength, or relative change of a magnetic field at a particular location.
