The Earth's core which is thought to consist of large quantities of molten iron in the center rotates with the earth creating a magnetism which protect us from solar flares e.t.c without this magnetism solar "winds" would wipe our atmosphere away from us in a matter of moments
A compass has a magnetized needle that can spin freely.
They may contain naturally occurring magnetic minerals.
Yes, when magnetic mineral grains in a rock form, they can become magnetized in the direction parallel to Earth's existing magnetic field. This is due to the alignment of the mineral grains with the magnetic field at the time of formation, resulting in the retention of this magnetization in the rock.
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.
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.
A compass has a magnetized needle that can spin freely.
A compass needle is a magnetized steel needle that aligns with the Earth's magnetic field. Its use allows for determining directions such as north, south, east, and west.
If a compass loses its magnetization, then it's no longer a compass; it's nothing but aneedle on a pivot, pointing in random directions.
The magnetic field of Earth induces the cans of food to have north and south poles, and so they are magnetized to some degree.
Some examples of materials that are more difficult to magnetize but tend to stay magnetized include hard magnetic materials like Alnico and certain types of ferrite. These materials have high coercivity, which means they require a stronger magnetic field to magnetize initially but can retain their magnetization once magnetized.
The device you are describing sounds like a compass. The magnetized needle aligns with the magnetic field of the Earth, allowing users to determine their direction relative to the north.
When you sail with a magnetized needle, it will point towards the magnetic north pole. This is because the needle aligns itself with the Earth's magnetic field, which is used for navigation purposes.
Yes, nickel can be magnetized.
No, lead cannot be magnetized.
No, copper is not naturally magnetized.

The not magnetized rod will be attracted by both of the magnetized rods.
