The best procedure to create a permanent magnet is to expose a ferromagnetic material to a strong magnetic field for an extended period of time, aligning the magnetic domains within the material to create a permanent magnetic field.
Heating a permanent magnet beyond its Curie temperature can demagnetize it by disrupting the alignment of its magnetic domains. It is best to avoid hitting permanent magnets as well, as this physical shock can also disrupt the alignment of the domains and potentially weaken the magnet's magnetic field.
Hitting a magnet can cause the magnetic domains within the material to become disordered, reducing its overall magnetic strength. Repeated impacts can also cause the magnet to chip or break, further affecting its performance. It's best to handle magnets gently to maintain their effectiveness.
The difference between an electromagnet and a bar magnet is that the bar (steel) magnet is always turned on, therefore always magnetic. The electromagnet is a magnet that is powerd by a battery so you can turn it on and off.
Yes, a magnet can be used to pick up staples from a carpet. Simply move the magnet over the areas where the staples are located, and they should stick to the magnet's surface. This method works best for larger staples made of a ferromagnetic material.
A magnet sticks to a refrigerator because the refrigerator door is made of a ferromagnetic material, such as steel. The magnet and the refrigerator door have opposite magnetic poles, causing them to attract and stick together.
Ultimately they are made of the right atoms spaced the right distance apart. Electrons are charged and have a spin and so create a magnetic field.

Any metal can be the core of an electromagnet, but some work better than others, and still others result in different effects. A copper cored electromagnet produces a repulsing force, as opposed to the attractive force of an iron core electromagnet.

a magnet that remains magnetized for only a small time interval as compared to a permanent magnet.
A non-magnetic material, such as paper, plastic, or wood, would best reduce the attraction between a magnet and iron. These materials do not interact strongly with magnetic fields, so they will create a barrier that decreases the magnetic force between the magnet and the iron.
BuckyBalls are the best
sharpie is the best type of permanent marker.
Electro magnets can be used to attract metals temperarily while permanent magnet would be used for compasses.

no a magnet isn't always at its best when hot. some magnets don't even work when its hot.
The best term to describe the space surrounding a magnet in which the magnet force acts is "magnetic field." The magnetic field is a region around a magnet where magnetic forces are exerted on other magnets or magnetic materials.
