A coil without core by a direct voltage supply through the flow meter.<\/span> Bring a small iron, eg clip, notice what happened.<\/span> Then fill the coil with an iron core, bring the little iron sebua, observe what happened.<\/span>

Interesting iron core iron clip with stronger than without an iron core, shown in Figure 1.116.<\/span> Tersearahkan iron molecules by a magnetic field generated by the coil.<\/span> Sehinngga iron nuclei have magnetic properties.<\/span> The strength of the magnetic coil current rises with the increase, but at a certain amount of current the magnetic force does not rise again (saturated).<\/span> Iron magnetic conditions on the same field strength in a few different materials.<\/span> In 1117 the picture depicted the condition, which is described density field (B) of the iron core of a coil in dependence on the field strength (H).<\/span>

Comparison with the magnetic flux density of magnetic field strength is called permeability.<\/span> Permeability is the product of a constant magnetic field with relative permeability.<\/span>
\n\"image\"<\/a>
\n \u03bc = permeability<\/span>
\n B = magnetic flux density<\/span>
\n H = magnetic field strength<\/span>
\n \u03bco = constant magnetic field<\/span>
\n \u03bcr = relative permeability<\/span><\/p>\n

Relative permeability is, how many times greater flux density of a coil between the core and without core.<\/span> The relative permeability of air is 1. The relative permeability of the ferromagnetic material amount of about several thousand, see Table 1.11.<\/span><\/p>\n

Table 1.11 The relative permeability \u03bcr max<\/span>
\n\"image\"<\/a><\/p>\n

When the flow of a coil around an iron core flux density is increased then it will go up.<\/span> Molecular magnets at the core to be drawn, strong magnetic field flux density is going up and will go up anyway.<\/span> Until the saturation level.<\/span> When the field strength is lowered, the flux density will also go down, but not as fast as the decline in field strength.<\/span> The field strength is lowered by minus (reverse flow) then the flux density will increase until it reaches the level of saturation negative negative (opposite direction).<\/span><\/p>\n

If then the field strength is lowered, it happened the same as on the positive side.<\/span> Until a strong graphic image field flux density function as shown below called histeristis meshes.<\/span> This is shown in Figure 1118.<\/span>

From the snares of hysteresis can be seen that in the end on the fiber will be left behind remanence.<\/span> If desired loss of remanence then do as was done earlier followed repeated with field strength gradually diminished until robust terrain is zero (Figure 1.119).<\/span>

This principle is applied to the elimination of magnetic tape, on cassette tape and reel and the like.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
