First, use a magnet to get the iron nails out because iron is a magnetic material and will be attracted to the magnet. Now what you have left is the water and oil. Fortunately, oil is less dense than oil and it will float on top of the water. Use a separating funnel to tap the water out from the bottom and collect it in a container. You can also use a spoon to get the oil out from a container which contains the oil and water since oil floats on the surface.
No, the iron nails inside the steel container will not be attracted to a magnet outside the container because the steel container will shield the nails from the magnetic field. Steel is not magnetic, so it will not affect the iron nails inside the container.
No, cooking oil cannot be removed from a mixture using a magnet. Cooking oil is not magnetic and therefore cannot be attracted or separated by a magnet. Other methods, such as filtration or centrifugation, are typically used to separate oil from a mixture.
It's possible that this will work, but the idea is highly inefficient at its best. Black sand is a general term, but there is black sand which has some iron oxide in it. This kind of iron oxide (there's more than one kind) is ferromagnetic, and it can be attracted by a magnet, as you'd expect. But there are problems. Should black sand be applied in a manner that distributes it widely, it can then "collect" oil on the surface of the particles and be attracted to a magnet bringing the oil with it (if the magnet is strong enough, close enough, etc.). But though the collection of the oil clinging to the black sand particles could be accomplished via a magnet, it would be easier to simply use absorbent materials to gather the oil. Also, there are a lot more bales of hay (or straw) around than bags of black sand. If the oil is concentrated enough for the black sand/magnet approach to be effective, absorbent pads would work a lot better to collect the oil. Particles of black sand can only collect material sticking to their very limited surface area (in spite of the large number of particles. Absorbent fibers trap far more oil through capillary action and "stiction" to and between the fibers than sand particles. Ask yourself this question: "Which will collect oil more efficiently, a hair (a fiber) or a particle of sand?" The hair has far, far more surface area than the sand particle, and hair fibers or some kind of fibers are at the heart of absorbent pads. Cat litter would work far better to collect oil (though it cannot be attracted by a magnet) than black sand. In addition to greater effectiveness, fibers are light, cheap and readily available. And they will float easily. Certainly if you had enough black sand, you could build a berm in shallow water outside a sensitive marsh and protect it that way. (Sand is being strategically deposited to perform this function as this answer is being written, by the way.) The black sand/magnet idea is a good one, but it is far too inefficient to work well. The physics is pretty clear, and thinking it through will reveal the truth.
One method to separate a small metal piece from oil is to use a magnet. By placing a strong magnet near the oil, the metal piece should be attracted to the magnet and can be easily removed. Alternatively, you can use a sieve or a filter to strain the oil and catch the metal piece.
According to Holt Science & Technolgy (Phisical science text book)pass a magnet over the mixture and the iron filings will be attracted to it.

Iron and other magnetic minerals are some of the most common elements on the planet. Soil and oil that contain these will leave a residue of them behind on a magnet.
No, the iron nails inside the steel container will not be attracted to a magnet outside the container because the steel container will shield the nails from the magnetic field. Steel is not magnetic, so it will not affect the iron nails inside the container.
You could just use a magnet, but if you're using the oil for cooking, just buy more oil. You're not going to get all the filings and you shouldn't ingest them.
Mixture containing 6 components: oil water salt sulphur iron calciumBy using the magnet you'll get iron out.Then you should centrifuge to get sulfur outand after pipetting the oil from the top layeradding hydrochloric acid should dissolve the calcium, after whichyou can remove the water by boilingto get crystallised salt at lastNote: calcium can not be collected UNchanged from this rather complex mixture by these simple methods.
Iron will float in oil in most cases. However, for iron to float in oil, it must have a density which is lower than the oil.
The dipstick has nothing to do with the low oil pressure light. It is just there to check the fluid level. The light will come on if low oil pressure is detected. Sometimes that is too late and damage will have already occured. Get a new dipstick asap. Try using a magnet to get the old one out. You can buy a magnet for this purpose at most auto parts stores. If you cannot get it out with a magnet, you will have to remove the oil pan.
No, cooking oil cannot be removed from a mixture using a magnet. Cooking oil is not magnetic and therefore cannot be attracted or separated by a magnet. Other methods, such as filtration or centrifugation, are typically used to separate oil from a mixture.
It depends. What kind of oil? Sesame seed oil? Motor oil?

Fish oil supplements contain adequate amounts of iron.
