get a magnet that attracts iron
Run a magnet over the mixture of nails and baby powder. Iron will be attracted by the magnet while baby powder will not.
Use a magnet to seperate the iron. Then, add water to dissolve the salt and float the sawdust. Skim off, sieve or filter the solution to seperate the sawdust. Let the water evaporate, leaving the salt behind.
the correct answer would be -( magnetic attraction of one part )
Mix the salt and powder together in water until the salt dissolves. Pour the mixture through filter paper to separate the powder from the water. Boil the water so it evaporates and leaves the salt behind. If the powder is iron, you can use a magnet to separate them rather than mixing in water.
by putting all of the substances on a sheet or plate and then using a magnet underneath to pull the iron fillings away. then for your table salt and white sand you just use small mesh and voila! all wrong ... 1st, use magnet to separate the iron filling from the mixture of sand with table salt 2nd add water to dissolve the salt from the mixture with the sand and filtrate the liquid sand has separated from mixture of salt 3rd place the the filtrate liquid to a burner with a evaporating dish, the water will be evaporate and the remaining residue would be the small crystal particles which is the salt.
The fillings align themselves according to the magnetic field created by the magnet. *See the related links to images of the fillings behaving this way, along with a drawing representing the magnetic fields to which the filings align. You can see how the fillings behave similarly in each of the different photos. (see also related question below)
you use a magent
Use a magnet to lift out the iron filings.
you an use a magnet to get the iron fillings out
use a magnet
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
The iron fillings are attracted by the magnet and separated from the sulphur powder.
All you have to do is put a magnet over the mess of sawdust and iron fillings and the iron fillings will get stuck to the magnet. Then their seperated
A magnet
use a magnet :)
Use an electromagnet.
Very easily, put a magnet on them it will attract the iron but not the aluminium.
