1. Two magnets are stuck together. What might you have to do to get them to separate? 2. Suppose you held two magnets a short distance apart, then let go. What would happen? 3. Think about the magnets in terms of energy. In which case do you increase the potential energy of the magnets? In which case do you increase the kinetic energy of the ...
Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together. Because of this, the magnet on top will be one magnet-height's distance farther away from the paper ...
Magnetic elements are attracted to a magnet. CLICK HERE to see how it works. Separating funnel. In this technique, two liquids that do not dissolve very well in each other (immiscible liquids) can be separated by taking advantage of their unequal density. A mixture of oil and water, for example, can be separated by this technique.
NEL 3.2 Separating Mechanical Mixtures 59 Floating and Settling Some parts of a mechanical mixture may fl oat or sink in water. If one part of a mixture is fl oating, you can skim it off the top using a spoon or a scoop. If one part of a mixture sinks (settles) in water, you
Sep 28, 2012· Two large magnet assemblies are affixed to opposite sides of a stainless-steel chute and attract ferrous contamination as material flows by the chute. The magnetic circuit is designed for an exceptionally deep reach into the product flow, which makes these separators effective at removing large, chunky tramp metal.
A simple description of how a mass spectrometer works. Note: All mass spectrometers that you will come across if you are doing a course for 16 - 18 year olds work with positive ions. Even if a few atoms in a sample of chlorine, for example, captured an electron instead of losing one, the negative ions formed wouldn't get all the way through the ordinary mass spectrometer.
Answer (1 of 2): 1. A simple magnet will draw the particles of iron away from the mixture. Any powdered sulphur adhering to the iron particles on the iron can be separated by placing the magnet and iron into a container of cold water, when the sulphur will float off. 2. Sulphur is soluble in carb...

Oct 23, 2020· In order to separate iron filling from sulphur,a horse shoe type magnet is moved on the surface of the mixture. The iron fillings are attracted by the magnet, they cling to the poles of the magnet and get separated. This process has to be repeated a number of times to achieve complete separation of iron filling.
Apr 17, 2011· If you put them in a tube so they stick end-to-end (north end of one on south end of the other, other ends far apart) at a distance the field strength is just the sum of the fields from the two magnets, double those from a single magnet. Again, the fields up closer are more complicated. Mike W. (published on 04/17/2011)
Quick Trick: Unstick Stuck Magnets: You bought a stack of super-strong magnets. You took off one magnet to test it out, then, satisfied, tried to put it back on the stack. Instead, you sent a plastic divider flying across the room and now have two magnets stuck together. And boy, are …
Before joining the magnets: Put on gloves! Place one magnet on a flat and stable surface. Keep the second magnet at a safe distance! Place one side of the wedge flat on top of this magnet. Keep a good grip on the wooden wedge and, from above, carefully place the second magnet on top of the wood. Now you can carefully slide the magnet to the tip ...
A large diversity of mechanical means are used to separate magnetic materials. During magnetic separation, magnets are situated inside two separator drums which bear liquids. Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate).
The magnet does not have distinct north or south particles on opposing sides. If a bar magnet is broken into two pieces, in an attempt to separate the north and south poles, the result will be two bar magnets, each of which has both a north and south pole. However, a version of the magnetic-pole approach is used by professional magneticians to ...
You could demonstrate how, or let the learners try, to separate a mixture of sand and iron filings by using a magnet. It might help to place the magnet in a small plastic bag so the iron filings are attracted to the magnet, but do not stick to it.
However, if you do move the magnets, then you need to give some energy. This energy is stored in the system because you cause a variation of magnetic flux: magnet 1 moving induce a variation of flux seen by magnet 2, and this will change the state of magnet 2, increasing its potential energy.
