The EFFECT of steel passing over a magnet can be detected and therefore recorded.
You can use a magnet to separate steel fillings from sulfur because steel is magnetic whereas sulfur is not. By passing a magnet over the mixture, the steel fillings will be attracted to the magnet and can be easily separated from the sulfur.
Aluminium and steel cans can be separated using a magnet, as steel is magnetic while aluminium is not. By running a magnet over a pile of cans, the steel cans will be attracted to the magnet while the aluminium cans will not, allowing for easy separation.
You can magnetize a paper clip by passing it repeatedly over a large magnet.
Contrary to popular belief, most metals cannot be magnetised. The only common metals that can be magnetised are iron, cobalt and nickel. Mild steel, an alloy that contains over 98% iron, can also be magnetised because of its high iron content. Some steels, such as some stainless steels, have larger percentages of other metals which prevent them from being magnetised the same way.
The tape would hold together, but the recorded material would be damaged.
A magnet can be used to separate iron dust from sulfur since iron is magnetic while sulfur is not. By passing a magnet over the mixture, the iron dust will be attracted to the magnet, leaving the sulfur behind.
No. The first use of Nikasil by Yamaha on the YZ appears to have been on the 1989 YZ125. One really easy way to tell is to use a magnet. Nikasil over an aluminum bore is non-ferrous where as the steel sleeve obviously is. If the magnet sticks, it is a steel liner.
Iron can be separated from a liquid clay solution by employing a magnetic separation technique. Since iron is magnetic, passing a magnet over the solution will attract the iron particles, allowing for their separation from the liquid clay.
A mixture of nails and sawdust can be efficiently separated using a magnet. By passing a magnet over the mixture, the ferromagnetic nails will be attracted to the magnet, allowing them to be easily removed from the sawdust. The remaining sawdust can then be collected separately, resulting in an effective separation of the two components.
To make an iron bar into a magnet you need to get a bar magnet and stroke the iron one way when you get to the end of iron take the magnet off and jump it back to the start and stroke repeat this several times and your bar will soon become magnetic. You can also change it into an electromagnetic by rapping a coiled wire tightly around it and send the current through the wire. The current will induce a magnetic field, causing the iron to magnetize temporarily. Lastly, you can heat the iron in a powerful solenoid field. As the iron heats up the regions become "free" to orientate with the field. The iron has to be heated to a orange/yellow glow before this is largely effective. The iron should then be allowed to cool in the presence of the field.
You can make a temporary magnet by rubbing a piece of iron or steel with a permanent magnet. This aligns the domains in the material, creating a magnetic field. However, this magnetism will fade over time as the domains become disorganized again.
Using a magnet: Iron filings are magnetic and can be separated from sulfur by passing a magnet over the mixture. The iron filings will be attracted to the magnet, allowing them to be removed easily. Using a solvent: Sulfur is insoluble in water, so the mixture can be dissolved in a suitable solvent where sulfur remains undissolved. The iron filings can then be filtered out from the solution, leaving sulfur behind.
