What happens when a magnet is places under the filter paper on which the mixture of sulfur and iron filings was placed? The filings 'stand up', but the sulfur does not. This is because iron filings are attracted to the magnet but sulfur is not.

Use. The principal use is as a dehydrating agent in the preparation of concentrated nitric acid.. Its fertilizer grade has 10.5% nitrogen and 9.4% magnesium, so it is listed as 10.5-0-0 + 9.4% Mg. Fertilizer blends containing magnesium nitrate also have ammonium nitrate, calcium nitrate, potassium nitrate and micronutrients in most cases; these blends are used in the greenhouse and hydroponics ...
A compass is a tiny magnet balanced on a point so it can turn freely. The magnet is attracted by the earth's magnetic north pole and always points in that direction. A good way to see how the magnet attracts is to do the following experiment. Take a strong bar magnet and putt a piece of pare over it. Then sprinkle some iron filings on the paper.

The higher the number, the better the shield. Low carbon steels have a Permeability of 1000 - 3000, while MuMetal can have values as high as 300,000 - 400,000. The saturation point is the flux density at which the material can not contain any more magnetic flux. Steel saturates around 22,000 Gauss, while MuMetal saturates at about 8,000 Gauss.
No If you want to read in detail: Ferromagnetism Ferromagnetism is a solid state phenomena, and it happens at a high energy state (in another words, less preferred) of the material. When you melt the material, the molecules will rearrange thems...
Mar 28, 2016· The magnetic field of a refrigerator magnet is more than 10 times stronger than the Earth's magnetic field. There are two units of measure for magnetic fields: gauss and tesla. One tesla equals 10,000 gauss. The Earth's magnetic pull is about .5 gauss. A 1 tesla magnet …
Jan 27, 2018· As demonstrated in the video, when a magnet is dropped through a coil of copper wire that isn't connected to itself, this reaction doesn't happen--the magnet drops straight through.
Oct 23, 2015· Oct 23, 2015· Trust Physics to come up with the most awesome combination of strange liquids ever - ferrofluid, which is that eerie, shiny black substance that forms weird 'spikes' when exposed to magnets, and glow stick goo. In the video above, we see what happens when you take this glowing liquid, mix it with ferrofluid, dim the lights, and break out the magnets.

Aug 04, 2016· Aug 04, 2016· Magnetic fields are created when electric current flows: the greater the current, the stronger the magnetic field. An electric field will exist even when there is no current flowing. If current does flow, the strength of the magnetic field will vary with power consumption but the electric field strength will be constant.
Aug 27, 2021· 1 · Can room-temperature superconductors transform from a tantalizing glimmer to practical materials? Every year, Ranga Dias pulverizes about $100,000 in diamonds, crushing them to a gray powder he tosses in the trash. It's worth it. The superhard gems were saced to achieve a goal researchers have chased for generations. Before their demise, pairs of the 2-millimeter-diameter …
