No, you cannot use a magnet to separate nickel chloride from lead as neither of these substances are magnetic. Nickel chloride is a compound composed of nickel and chlorine atoms, while lead is a heavy metal. Separating them would require a different method such as chemical reactions, filtration, or distillation based on their physical and chemical properties.
You could use a magnet to separate a collection of metal objects from a tomb. Iron object and other ferrous metals will stick to the magnet while some other types of metals will not.
An hypothesis is an idea, notion, conjecture, assertion or statement about reality. The activity we call science is about putting forward and testing hypotheses. For example, you could test your notion that nickel might be magnetic by putting it near a magnet. If it was clearly attracted, you could suggest that "nickel is magnetic" was not just an hypothesis but a fact. If not, you might test with an even stronger magnet, and so on. Testable hypotheses, especially those that help to explain why things act the way they do, are important because they prompt activities which can improve scientific knowledge.
by keeping another magnet or attractive force
Not exactly. All pieces of the magnet retain their ferrous properties, but if they were (for example) dropped, then the shock of the fall could potentially make them lose a bit of magnetism. Extreme temperature changes and high power electric discharges could also decrease the power of the magnet.

With a magnet. Iron is ferromagnetic
use a magnet
yes, with a magnet
One way to separate iron nails from copper tacks is to use a magnet. The iron nails will be attracted to the magnet, allowing you to easily separate them from the copper tacks.
You can use a magnet to separate iron from sulfur since iron is magnetic while sulfur is not. By using the magnet to attract the iron particles, you can separate them from the sulfur.
With a magnet : only iron will be attracted.
One way to separate silver chloride from barium chloride is by adding sodium chromate solution. Silver chloride will form a red precipitate while barium chloride will not react. The precipitate can then be filtered out to separate the two compounds.
One could use a magnet to separate sewing pins from carpet. Using a magnet also eases pin clean up on other surfaces as well.
If it is a simple mixture of Fe and S you can use a magnet to separate iron. Of course, the method is not valid for an iron sulphide.
One way to separate iron filings and aluminum filings is by using a magnet. Since iron is magnetic but aluminum is not, you can use a magnet to attract the iron filings and separate them from the aluminum filings easily. Simply pass the magnet over the mixture, and the iron filings will be attracted to the magnet, allowing you to separate them from the aluminum filings effectively.
Water is deleted by heating and evaporation.
You can take a magnet and put it around it and it will work
