A magnet is useful in generating electricity because a magnetic force moves?
electrons
When would you use a magnet to separate the parts of a mixture?
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.
Why is it useful for food manufacturers to use magnets?
Magnets are used to remove any ferrous metal from the food product
What does a magnet do to a paperclip?
A paperclip attracts a magnet ,a magnet attracts a paperclip.
Is pyrrhotite magnetic?
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.

How a compass works and why it is useful?
A compass has a magnet that points north, according to the Earth's magnetic field. It is useful, precisely, to find out where north is.A compass has a magnet that points north, according to the Earth's magnetic field.

electrons
Is magnet useless or useful?
Useful - even before humans discovered compasses and "electric" motors, the Earth's magnetic field protected our atmosphere.
Why is a magnet useful in generating electricity?
As Faraday discovered, turning a magnet in a coil of wire generates electricity. This is how even today electricity is created, but we use water to turn the magnets in hydroelectricity and so on. It is useful because it is very efficient and it has a mechanical advantage: the force needed to turn the magnet is lss than the force generated by the magnet turning. So basically, to sum it up, the only way to generate electricity is wih a magnet and a solenoid (coil)
What is a electromagnetic?
An electromagnet is a magnet carrying an electric current. This can be useful for many things. eg, door bells.
