Magnets of different strength are used.

Permanent magnets are typically made from materials such as neodymium iron boron (NdFeB) and samarium cobalt (SmCo). Neodymium magnets are known for their strong magnetic properties and are widely used in various applications, while samarium cobalt magnets offer high resistance to corrosion and can operate at higher temperatures. Both materials are essential in creating strong, durable magnets used in everything from motors to electronics.
Super magnets, such as neodymium magnets, are used in various applications like electronics, medical devices, and industrial machinery. They are commonly found in headphones, hard drives, MRI machines, and magnetic separators due to their strong magnetic properties and small size.
Electronics use electricity for power while electromagnets are magnets created by electricity.

To use strong magnets for hanging objects securely, you can attach a strong magnet to the object you want to hang and then place another strong magnet on the surface where you want to hang the object. The magnets will attract each other, creating a secure hold for the object. Make sure the magnets are strong enough to support the weight of the object.
Sticking things on refrigerators, some toys have magnets, there are magnets in computers and in TVs, certain doors have magnets, and most electronics have magnets.
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.
The Rust affects the magnet. The magnetic energy won't work as well cause it has to work thru the rust. So no, rusty magnets are not as strong as a nonrusty magnet
depends on the size of the magnet
Some magnets are stronger than others, making them harder to pull apart. For strong magnets, you can pull the magnets sideways to get them apart.
Neodymium magnets are the strongest type of permanent magnets available, with a much higher magnetic strength compared to other types of magnets like ceramic or alnico magnets.
