What else can I help you with?
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.
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.
What is Something that has two poles is describes as?
A magnet. It is described as a Magnet.
A magnet is useful in generating electricity because a magnetic force moves?
through a wire coil to induce an electric current in a process known as electromagnetic induction. As the magnet moves relative to the coil, the changing magnetic field creates an electric current. This current can then be harnessed to generate electricity.
Would a screen be useful for separating a mixture of gravel and diatomaceous-earth?
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!).
How is magnet useful to refrigerator?
its not useful for the refrigerator its useful for humans only....
Do magnets lose their power?
No.If you break the magnet, it is still a useful magnet.
How is refrigerator magnet used?
its not useful for the refrigerator its useful for humans only....
How is a generator useful?
it uses electricity to create a magnet
How is generalizing useful?
it uses electricity to create a magnet
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.

What is the most useful object to help make a simple compass?
A magnet.
Is magnet useless or useful?
Useful - even before humans discovered compasses and "electric" motors, the Earth's magnetic field protected our atmosphere.
What is a electromagnetic?
An electromagnet is a magnet carrying an electric current. This can be useful for many things. eg, door bells.
How are magnets useful for recycling household wastes?
A magnet can sort the ferrousmetalse.g., iron and steel, from the feed stream.
What is the significance of the magnetic field of a permanent magnet in relation to its properties and applications?
The magnetic field of a permanent magnet is important because it determines the magnet's strength and direction. This field allows the magnet to attract or repel other objects, making it useful in various applications such as electric motors, generators, and compasses.
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)
