The best place to locate an air separator in a hydronic system is where the water temperature is high and the pressure is low. The solubility of the dissolved gases in the water is lowest at these conditions. For a heating system, the ideal location is at the outlet of the heat source. For chilled water systems, locate the separator in the ...

3.4.1 Eddy Current Separators. Eddy currents are a manifestation of electromagnetic induction occurring when a magnetic field is applied to a conductor. If the magnetic induction Β in a material changes with time, a voltage is generated in the material, according to the equation. - dB dt = V A.
** The magnetic sands are removed by two separate magnetic fields located inside the magnetic wheel. This field is to the side of the feed so as the feed drops through the …

•Flow rate: Magnetic separators perform best when the contamination is presented to the surface of the separator. It is best to select a magnetic separator configuration that provides for a thin …
Eddy current separation technique is used for separating metals from nonmetal component; for example, aluminum from glass, which cannot be done by gravity methods as the difference in the densities of aluminum and glass is very small. Other applications will be described in Chapter 7 on Metal Recycling. A schematic representation of eddy current …
One experiment Faraday did to demonstrate magnetic induction was to move a bar magnet through a wire coil and measure the resulting electric current through the wire. A schematic of this experiment is shown in Figure 20.33. He found that current is induced only when the magnet moves with respect to the coil.
13. The DC coil relay has a resistance from the copper wire typically used. The current is limited by that resistance. AC coil relays have inductance as well (the DC relays have inductance as well, of course, but it does not affect the 'on' current). They also typically have a shading ring that acts as a shorted turn in order to cause a ...

Tuning inductors can be either air-, ferrite-, or powdered-iron-core coils. The air-core coils are not adjustable unless either an expensive roller-contact mechanism or clumsy taps on the winding of the coil are provided. However, the ferrite- and powdered-iron slug-tuned core coils are adjustable. Figure 4-1 shows one form of slug-tuned ...

magnetic field in the object. When the pulse's magnetic field collapses, causing the reflected pulse, the magnetic field of the object makes it take longer for the reflected pulse to completely disappear. This process works something like echoes: If you yell in a room with only a few hard surfaces, you probably hear only a very brief echo, or
publicly reply to Ted Mooney's post ^. A. Check out eddy current separation on the web; this equals a gold magnet! Non-magnetic conductors e.g. gold, silver, copper, etc. can have electric fields inducted into them. These electric fields attract and repel just as do magnetic fields.
A magnetic separator consists of a powerful magnet that is placed or suspended from a ceiling or device. Materials can be passed over a table top magnetic separator, while suspended magnetic separators often hang over a material to remove its impurities. Magnetic separators can also be cylinders through which objects pass.
Inductance-type tramp metal detection system, make use of an oscillating magnetic field produced by a wire coil. When a conductive or magnetic piece of tramp metal passes over the coil, the oscillations change. This change is detected by the electronics and an alarm is tripped.
The most magnetic force is exerted when a magnet can attract a piece of iron that forms a closed path for magnetic flux when it is added to the path. The coil of an electromagnet has very little resistance, so only a very small voltage is required to drive a lot of current through it. All batteries have internal resistance.
