Yes, magnets are useful for many applications including holding objects together, generating electricity, and even medical imaging.
A magnet would only be useful if some component(s) of the mixture were ferromagnetic (e.g. iron, nickel, cobalt, magnetite), in which case such component(s) would stick to the magnet and the remainder would be left behind.
Some screwdrivers are magnetic. Therefore a bit more expensive. But some arent magnetic, so if you choose a screwdriver, I recommend a magnetic one (P.S Im a 12 year old kid that found this information by watching Bill Nye the Science Guy)
Yes, although only weakly. It will move a compass needle or attract a magnet. This property is useful for distinguishing pyrrhotite from other brassy colored sulphide minerals.
A magnet. It is described as a Magnet.
Screwdrivers can have weak or strong magnetism.

No.If you break the magnet, it is still a useful magnet.

Yes, although the magnet may not be strong enough to move the screwdriver towards it. Screwdrivers are made of metal, meaning they are magnetic.
I don't know why a magnet would harm a laptop computer, some repair techs even us magnetic screwdrivers when working on laptops. I guess if you were to place a strong magnet next to the hard drive it might harm it.
A magnet.
Useful - even before humans discovered compasses and "electric" motors, the Earth's magnetic field protected our atmosphere.
Screwdrivers can be categorized by their tip type, including flathead (slotted), Phillips, Torx, and hex. They can also be named based on their size, such as precision screwdrivers for small screws or larger, heavy-duty versions. Additionally, there are variations like electric screwdrivers and ratcheting screwdrivers, which offer specific functionalities. Lastly, some screwdrivers are named based on their intended use, like cabinet screwdrivers or jewelers' screwdrivers.
