What is more often used in magnets aluminum or nickel?
Nickel is used more in magnets
Which is most often used in magnets aluminum or lead?
Aluminum is not typically used in magnets. Lead is also not commonly used in permanent magnets due to its low magnetic properties. Instead, materials like iron, nickel, and cobalt are more frequently used in magnets.
Will aluminum sink or float in mercury?
Aluminium will always float in Mercury. The mass of the Aluminium is irrelevent. If you think of a more common example does it matter how big the piece of wood is as to whether it floats in water? Aluminium floats in Mercury because it is lighter than the same voluime of Mercury just as wood floats on water because it is lighter than same volume of water.
What are the 3 pure metals which don't stick to magnets?
The three pure metals that do not stick to magnets are aluminum, copper, and gold. This is because their atomic structure does not allow the alignment of magnetic domains necessary for magnetism to occur.
Would a block of aluminum float or sink in a pool of mercury at room temperature with a density of 13.6?
A block of aluminum will float on a pool of mercury at nearly any temperature (except at extremely elevated temperatures (above 350 °C) where mercury is no longer liquid) The density of aluminum is 2.70 grams per cm3, whereas the density of mercury is 13.53 grams per cm3. Therefore mercury is more than 5 time more dense than aluminum! Anything that is less dense than a liquid will float in that liquid. Not only would aluminum float but it float with only 1/5 of it's volume submerged.
What is the difference between an alnico magnet and ferrite magnet?
The term alnico is derived from the names of three metals, aluminum, nickel, and cobalt, which can be used to make an alloy that has useful magnetic properties. Ferrite is a form of iron. Alnico magnets are more powerful and more expensive than ferrite magnets.
Is mercury the lightest substance in between aluminium lead and copper?
At "normal" temperatures, Mercury is denser than any of those substances ... slightly more so than lead, somewhat more so than copper, and a lot more so than aluminium.
What metals are used in magnets?
Most magnetic alloys are based on one or more of the following:ironnickelcobaltHigh field strength modern alloys also contain rare earth metals.
Does a soup can stick to a magnet?
Until the beginning of the 21st Century, most canned goods were sold in steel cans, which were magnetic. But more and more items are being marketed in all-aluminum cans. This has made obsolete the "lid magnets" on electric can openers.
Why is mercury thermometer not allowed in air flight?
Mercury and aluminumhttp://en.wikipedia.org/wiki/Mercury_(element)#Mercury_and_aluminiumMercury readily combines with aluminum to form a mercury-aluminum amalgam when the two pure metals come into contact. However, when the amalgam is exposed to air, the aluminum oxidizes, leaving behind mercury. The oxide flakes away, exposing more mercury amalgam, which repeats the process. This process continues until the supply of amalgam is exhausted, and since it releases mercury, a small amount of mercury can "eat through" a large amount of aluminum over time, by progressively forming amalgam and relinquishing the aluminum as oxide.Aluminium in air is ordinarily protected by a molecule-thin layer of its own oxide, which is not porous to oxygen. Mercury coming into contact with this oxide does no harm. However, if any elemental aluminum is exposed (even by a recent scratch), the mercury may combine with it, starting the process described above, and potentially damaging a large part of the aluminum before it finally ends.[48]For this reason, restrictions are placed on the use and handling of mercury in proximity with aluminum. In particular, mercury is not allowed aboard aircraft under most circumstances because of the risk of it forming amalgam with exposed aluminum parts in the aircraft.
What is more durable Aluminum or steel doors?
Steel is a harder and more durable metal than aluminum. Therefore, steel doors are often more durable and more difficult to damage than aluminum doors.
Why do big magnets pick up little magnets?
because it is bigger than the little magnets and has more power than the little magnets do.
