A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction. The magnetic flow meter requires a conducting fluid, for example, water that contains ions, and an electrical insulating pipe ...
A 1996 study by Lawrence Livermore National Laboratory found no significant effect of magnetic water treatment on the formation of scale. As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental ...
The water circulating around the heating system picks up bits of sludge (or magnetite) which can build up. The magnetic filter attracts all these bits of debris with a strong magnet as the water flows around it, preventing a build-up of sludge in the pipework or in the boiler. [11]
The current is fed through a conducting liquid. Two permanent magnets are arranged to produce a magnetic field B ap as shown in the figure. The supplied current has a current density (J) and the magnetic field associated with this current can be called "Reaction magnetic Field (b rc)". The two magnetic fields B ap and b rc attempt to align with ...
In order to incorporate magnetic systems into the first law of thermodynamics, it is necessary to formulate the concept of magnetic work. The magnetic contribution to the quasi-static work done by an arbitrary magnetic system is [1] = where is the magnetic field and is the magnetic flux density. [3]

Avoid storing your credit card near magnets or other magnetic items. If your purse or wallet has a magnet on it, ensure the magnetic strip on your card faces away from the magnet to help avoid damage.
[8] [7]: 25 The connection between the fluid and magnetic field fixes the topology of the magnetic field in the fluid—for example, if a set of magnetic field lines are tied into a knot, then they will remain so as long as the fluid has negligible resistivity. This difficulty in reconnecting magnetic field lines makes it possible to store ...
