Galvanometer
Galvanometer is the historical name given to a moving coil electric current detector. When a current is passed through a coil in a magnetic field, the coil experiences a torque proportional to the current. If the coil's movement is opposed by a coil spring, then the amount of deflection of a needle attached to the coil may be proportional to the current passing through the coil.

Physical sorting – The Eddy current separation method
Previous Next • Physical sorting – The Eddy current separation method. The most obvious example of sorting is that of using magnets to attract ferrous scrap. Magnetism occurs in iron due to unpaired electrons in the dorbital giving each iron atom a magnetic these moments are aligned due to the interaction of the dorbitals, giving an overall magnetic .

How WalkThrough Metal Detectors Work
Mar 09, 2018 · How They Work. Walkthrough metal detectors typically use pulse induction (PI) technology. The PI systems send powerful, short bursts (pulses) of current through the coil of wire. Each pulse generates a short magnetic field. When a piece of metal passes through the magnetic field, a reflected magnetic field is created.

Theory of Magnetic Flow Meters | Emerson US
Once powered, a magnetic field is formed between both coils. When the pipe is full and the fluid begins to flow, the force of the magnetic field causes the negatively and positively charged particles of the fluid to separate as they pass through the magnetic field. This separation causes an induced voltage between the electrodes and sensor.

Magnetic Resonance Imaging (MRI)
Magnetic Resonance Imaging (MRI) is a noninvasive imaging technology that produces three dimensional detailed anatomical images. It is often used for disease detection, diagnosis, and treatment monitoring. It is based on sophistied technology that excites and detects the change in the direction of the rotational axis of protons found in the water that makes up living tissues.

How does it work?: Magnetic resonance imaging
Jan 05, 2002 · Magnetic resonance imaging (MRI) uses the body's natural magnetic properties to produce detailed images from any part of the body. For imaging purposes the hydrogen nucleus (a single proton) is used because of its abundance in water and fat. The hydrogen proton can be likened to the planet earth, spinning on its axis, with a northsouth pole.

Solenoid Valve
Solenoid Valve How They Work. A solenoid valve is an electrically controlled valve. The valve features a solenoid, which is an electric coil with a movable ferromagnetic core (plunger) in its center. In the rest position, the plunger closes off a small orifice. An electric current through the coil creates a magnetic field.
