the arms of the magnetometer is in perpendicular direction along the alluminium pointer
A magnetometer
it is a method for measuring the magnetic susceptibility of a samples using special tools such as vibrating magnetometer
Put a piece of iron close to it, if it is magentic an atractive force will apear. If you want to distinguis what kind of magnetic properties your object has (ferromagnetic, paramagnetic),... then you should use a magnetometer like for example SQUID.
Magnetic ink is exactly what the name indicates; it is a kind of ink which is both visible to the eye (it's black) and has a magnetic field that can be detected with the right kind of magnetometer. It is used in the coding on the bottom of checks, known as routing numbers, so that it can be read both by people and by computers.
A magnetometer is a device that is used to detect magnetic fields on the seafloor. It was invented by Sheldon Breiner.
the arms of the magnetometer is in perpendicular direction along the alluminium pointer
A magnetometer.
the arms of deflection magnetometer is in east-west direction along the alluminum pointer
A magnetometer is an instrument that measures magnetic forces and the magnetization of magnetic material. A magnetometer can be found in cell phones and metal detectors.
The induction magnetometer detects temporal variation of the geomagnetic field based on Faraday's law of magnetic induction.
