Rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields. You can make substitutions but you won't get the same strength of magnetism.
An electromagnet. It can have any intensity you want, within reason. And it won't get irretrievably stuck to your fridge.
You can use neodymium magnet (also known as NdFeB, NIB, or Neo magnet) which is the most widely-used type of rare -earth magnet, is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure.
Electro Magnets are the controllable type of magnet used. It may be possible but not practical to use rare earth magnets.
no it is not . a temporary magnet is used instead. If you use a permanent magnet, the doorbell will keep on ringing

your TV, smart phone, car, head phones, speakers all use rare earth elements. there are many types of rare earth elements that all have different uses.

So that the load can be dropped by turning off the current.
A compass would not work without a magnet. Inside the compass is a magnet which moves to line up with the Earth's natural magnetism. The north pole of the magnet is attracted to the south pole of the Earth. As such, the magnet moves to always be lining up in this way. When you use a magnet, you can see this in action as the needle moves around to always point northward and from knowing this, you can tell which way you are facing.How_does_a_compass_use_magnetismHow_does_a_compass_use_magnetismHow_does_a_compass_use_magnetismRead more: How_does_a_compass_use_magnetism
There is no legitimate way to get 1000 rare candies. Instead you would have to use a cheat such as Action Replay.
They use the fact that the earth acts as a giant magnet so that compasses point towards the north pole.
China, because they got the rare earth elements.
