A magnetic sweeper would be useful in a situation when someone needs to pick up and find metal items, such as iron. This may be useful in steel work companies.
A cordless vacuum sweeper is most useful for small spills and small area clean up. They can also be used in hard to reach places where the regular vacuum cannot reach.
When purchasing a magnetic sweeper it would be best to read the information about the sweeper very carefully. I would recommend purchasing one at an office supply store, because they are very knowledgeable about computer safety and compatible products.
It depends on the application. Electromagnets can be turned on and off, allowing for more control, while permanent magnets offer constant magnetic strength. Electromagnets are often preferred in situations where the magnetic force needs to be adjusted or varied.

There is no reason you cannot. It may work best to mount only the sweeping unit and not its handle, as that would mean an extra pair of wheels to steer.
The property that would be most useful in telling hematite and magnetite apart is magnetism. Magnetite is strongly magnetic, whereas hematite is not magnetic. This distinction can help differentiate between the two minerals.
A magnetic compass depends on Earth's magnetic field for orientation. In space, there is no magnetic field to interact with, so a magnetic compass would not be useful for navigation. Other orientation systems, like gyroscopes or star tracking sensors, are used instead in space.
Wafer seals are available to buy online or around your community. If you are looking for large bulk, I would try waferseals.com. Also, the UPS or FedEx store has these products and would more than likely sell in bulk for you.
No. A compass is a useful tool on Earth because the needle aligns with Earth's magnetic field and we know the shape of that field. There would be no such field in outer space.

yes it would. you could also separate it with a magnet then the gravel would stick to the magnet. +++ Magnetic gravel? You can separate diatomaceous earth from gravel simply by sieving. Gravel is not magnetic (unless it happens to be a magnetic ore of iron!).
You might find a model that has a release system, but most you just carefully pick the items off of the sweeper. If you have a hard time finding one, many hardware stores now carry them.
