A compass is a device that uses a magnetic needle to show you which way is north, helping you navigate and find your way when you are lost.

How can a north poles of a magnet help when you are lost?

The north pole of a magnet can help when you are lost because it can act as a compass. When suspended freely or allowed to rotate, the north pole of a magnet will align itself with the Earth's magnetic field, which points towards the North Pole. By observing the direction in which the north pole of a magnet points, you can determine which way is north and navigate your way.

Will steel nails that are joined by a magnet remain joined if the magnet is removed?

In general, steel nails will not remain "joined" if a magnet touching them is removed. It is important to note that nails affected by a magnet retain a weak "impression" of the field and remain slightly magnetic. But the magnetic field "impressed" on the nails will be quite small and will not hold the nails together once the magnetic is removed.


How do you destroy a magnet?

The same way you destroy anything else. melt it in a furnace is the only way because if you chop it one end will be south and the other will be north If you mean "How do you remove the magnetism from a permanent magnet?" There are several ways. You can heat it past its Curie Point. For iron that is about 800C. Stroking one magnet with another in a random fashion will sometimes work. Hammering it will usually work.


When Liquid helium is cut off by a power loss what happens to a MRI magnet?

When power is lost, the liquid helium in an MRI magnet will begin to warm up and boil off. This can lead to a rapid increase in pressure inside the magnet, causing a potential risk of an explosion if not handled properly. The magnet will also lose its superconducting properties, rendering the MRI machine unusable until it is refilled with liquid helium and re-cooled.

What kind of magnet is a magnetized nail?

A magnetized nail is a temporary magnet, known as an induced magnet. It becomes magnetized when it comes into contact with a permanent magnet, aligning its magnetic domains in the same direction. This temporary magnetism can be lost if the nail is no longer in contact with a permanent magnet.

How does a magnet might help you find directions if you are lost in the forest?

A magnet can help you find directions in a forest by using it to determine which way is north. By suspending a magnet on a string and allowing it to freely move, one end of the magnet will point towards the Earth's magnetic North Pole, indicating the north direction. This can help you orient yourself and make your way out of the forest.

How to cause a magnet to lost its magnetic power?

A magnet can lose its magnetism if exposed to high temperatures. If heated above the point called the Curie temperature, a magnet will lose its magnetism.

How could you use a bar magnet to find your way out the forest?

I would think the usual reason of getting lost is not following a straight path (going in circles). Human tends to favorite one side (because of inner ear imbalance), so the walking path is curved, and eventually you are back to the starting point. A compass will have set a more-or-less straight course. How to construct a compass with a bar magnet? I can think of two ways. You can tie the magnet to a string and let it settle with the magnet at the bottom of the string. The alternative is to find a puddle every so often, drop the bar magnet in the water, and let it show the way (if the magnet floats; it will be better if you can find a container to put water in and bring it with you).
