The earth's magnetic properties are due to its molten iron core.
Yes, a compass needle is essentially a magnet because it aligns with the Earth's magnetic field due to its magnetic properties.
An example of a permanent magnet is a refrigerator magnet. These magnets are made from materials with high magnetic properties, such as iron, nickel, and cobalt, and retain their magnetic field without the need for an external power source.
The Earth is a naturally occurring magnet (it has a north and south pole. The mineral magnetite is also magnetic.
A magnet ie. the the ones on your fridge are made by manufactures pushing electrical current through ferrous metals causing them to have magnetic properties. Rare earth magnets are naturally occurring elements that have magnetic properties by themselves.
Nothing happens, except that now you have two magnets. The poles of a magnet are not actually localized at the two ends of the magnet but are inherent to the magnetic properties of the magnet. As the magnetic properties are not altered by a modification of the magnet such as cutting it in half, there will be no effect on the poles of the magnet.
Not a magnet, no. But it does attract the Earth and this is due to gravity.
No, rare earth magnets do not stick to gold because gold is non-magnetic. Rare earth magnets are attracted to materials that have magnetic properties, such as iron and steel.
Ferromagnetic materials, such as iron, nickel, and cobalt, are attracted to a magnet due to their aligned magnetic domains. Other substances like steel and some alloys containing rare earth metals also exhibit magnetic properties and can be attracted to a magnet.
No. While electricity and magnetism are closely connected, the poles of a magnet no not correspond with electrical charges.
They are round. And they are magnetic. Without a specification for the magnet nothing more can be assumed.
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
