They use a powerful electromagnet. An electromagnet is essentially a coil of wire. When an electric current is passed through the wire, a magnetic force is created inside the coil. So to make a magnet, they rap the raw materials (special combinations of metal) in a wire and pass a current in the wire for a certain time. When the current is shut off, the material inside retains the magnetic properties and becomes what we call a Magnet.
Bar magnets display a characteristic type of charge called magnetic charge. These charges create a magnetic field around the magnet and can interact with other magnets or magnetic materials in their vicinity.
The type of household magnet you are referring to is most likely a neodymium magnet, which is a strong magnet that can repel or attract other magnets. These magnets are commonly used in household items like refrigerator magnets. If one magnet is repelling another, it means they are oriented in such a way that their magnetic fields are pushing against each other, creating a repelling force.
Usually magnets attract any iron based metals. Magnets usually only attract or repel other magnets
A plastic straw can stick to a magnet because it is made of a type of plastic that is attracted to magnets. However, plastic is an insulator and does not conduct electricity.
A neodymium magnet is a type of magnet that is unlikely to lose its magnetism. These magnets are made from a combination of neodymium, iron, and boron, which results in a very strong and durable magnet with high resistance to demagnetization.

Neodymium magnets are the strongest type of permanent magnets available, with a magnetic field significantly stronger than other types of magnets like ceramic or alnico magnets.

all magnets

only one... but there are difrent shapes...

Yes that works but first you should design a homopolar magnet because there are no homopolar magnets built, yet !
The iron nail would stick to a magnet. Copper is not attracted to magnets.

Magnets can lose their magnetic properties at temperatures above their Curie temperature, which varies depending on the type of magnet.
The strongest type of magnet typically found in a normal household is a neodymium magnet. These magnets are known for their strength and are commonly used in various household items such as refrigerator magnets and magnetic clips.
