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.
To drill a hole in a rare earth magnet, you will need a strong drill bit made of materials like tungsten carbide or diamond. Secure the magnet firmly in place using a vice or clamp to prevent it from moving during drilling. Use a slow speed and steady pressure to prevent overheating and damage to the magnet. Wear eye protection and work in a well-ventilated area.
The north pole of a magnet is attracted to the Earth's geographical North Pole, and the south pole is attracted to the Earth's geographical South Pole. You can also use a compass to find the north and south poles of a magnet - the needle will align with the north pole of the magnet.
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.

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.
Electromagnets are typically used when constructing a magnetic crane. This type of magnet relies on an electric current to generate a magnetic field, allowing the crane to control the lifting and moving of magnetic materials.
China, because they got the rare earth elements.
Earth's magnetic field created by earths magnets deflects cosmic rays which damage our biosphere.
A. Compasses typically use a permanent magnet.
