how does bimetallic strip use in irons?
488946
The length of any metal increases as the temperature rises. \n\nThe increase in length, for the same initial length is different for different metals for the same increase of temperature.\n\nIn bimetallic strips, two metals strips of same length are placed one over the other and are riveted at their ends.\n\nWhen these strips are heated, both strips increase in lengths but one increases more than the other.\n\nBut, as the ends are fixed, to accommodate the increase in length, both bend into arcs of a circle, the less increased strip form the  inner arc and the other form the outer arc.\n\nThis bimetallic strip is in contact with another strip and they are in series with the heating element of the iron. \n\nThis second strip can be depressed at will by means of a screw which can be operated externally.\n\nAs the temperature increases the bimetallic strip begins to bend but it is in contact with the second strip till a particular temperature reaches which is determined by the adjustment of the screw.\n\nWhen that temperature is reached the second strip ceases its contact with the bimetallic strip.

I'm not sure anyone really "know" but there are many teltail clues.  Not all materials are magnetic except perhaps under very powerful magnetic fluxes (MRI's?) but all atoms of materials do have one or more electrons orbiting their nuclii.  We know that electrons can be directed by magnetic flux, perhaps in a TV picture tube, etc.  Therefore, the number and arrangements of electrons of the atoms differ and some create magnetic properties (dipoles or two different poles).  If an iron bar is heated to a high temperature all the iron atoms in the bar are permitted to spin around willy-nilly.  If the bar is then cooled while exposed to a strong magnetic flux (electromagnet?) all its dipoles will align uniformly with the external flux like the needles of compasses aligned with the earth's flux.  When cool, the magnet exhibits the combined strength of all the dipoles that were previously working against each other.  We know that atoms repel each other because of their electrons (and even their nuclii must be forced together to fuse because of protons) like basketballs with ballbearings at their centers, where the skins are made of rapidly orbitting electrons.  Whereas the basketballs would repel each other in any given positions, actual atoms in iron crystals repel directionally and they which can attract or repel a free electron.  The magnet has collectively directed their combined force.  If each dipole has a North and South pole, we would expect the entire magnet to also have a North and South pole, and for like poles to repel, just as in the individual dipoles.  Hope that helps a little.

If you are doing it in a laboratory setting, you can mix it with carbon and reduce it to the metal. You will need high temperatures, though.

Obviously, Cobalt, Iron & Nickel.But its the alloy Alnico used to make permanent magnets.

It's an iron bearing oxide compound used as an abrasive.\n\nIt's only one of the abrasives in Emery Cloth.\n\nIt's also used as a powder in comercial applications, or in a colodial suspension for lapping compounds..

Magnetic materials are basically used as support structures.  Iron is used in skyscrapers.  If you have a VCR, then the tape that you watch is actually covered with iron filiments that are aligned by magnetism, and are then read by the VCR heads.  there are many more uses, but these are the ones that come right off hand.  for more look at the link, and do a web search using a search engine

You could try passing it through carbon, but that may also remove iron.  You would need to try it with known solutions.\nYou may need to go to AA or ICP analysis.

its makes for versatile application of the particular element..for instance graphite allotrope of carbon can be used for pencil lead

it's either copper or iron.  i don't remem ber exactly which one.

very poor syntax of your question......... \n\nI guess you want to know what two different metals together can make.....\n.... a thermostat\n\nthe two metals expand/contract at different rates causing a "bend" in the Bi-metal strip which will  open/close a contact switch and turn on/off the air conditioner or heater.

You should find that under the ASTM Manual for steel. Your engineering department should have a copy, otherwise try finding it on line.

Yeah, that's part of the design of the irons, supposed to make them more forgiving. See here for info:\n\nhttp://www.golfdigest.com/hotlist

Most likely it'll fit in between your 2 and 3 iron somewhere. \n\nIt's not really meant to replace an iron, it's more of a supplement, to be used from bad lies and where you really need to hit the ball high.

mixture of iron and carbon produces steel but there may be some chromium in it.

Silicon is essential to making of grey cast iron as opposed to white cast iron. Silicon causes the carbon to rapidly come out of solution as graphite, leaving a matrix of relatively pure, soft iron. Weak bonding between planes of graphite lead to a high activation energy for growth in that direction, resulting in thin, round flakes. This structure has several useful properties.\n\nThe metal expands slightly on solidifying as the graphite precipitates, resulting in sharp castings. The graphite content also offers good corrosion resistance.\n\nAlso A famous (and very large) example is the Iron Pillar of Delhi, erected by order of Kumara Gupta I around the year AD 400. However, unlike stainless steel, these artifacts owe their durability not to chromium, but to their high phosphorus content, which together with favorable local weather conditions promotes the formation of a solid protective passivation layer of iron oxides and phosphates, rather than the non-protective, cracked rust layer that develops on most ironwork.

Use a magnet. Iron is attracted to it, lead is not.
