Permanent magnets are those objects that are magnetized and will stay magnetized forever. One can make a permanent magnet by taking a hard ferromagnetic substance, like hard iron, lodestone, cobalt, and a number of rare earth metals, and magnetizing it strongly. Soft ferromagnetic substances may gain a temporary magnetic field, but will tend to lose it rather quickly. Electromagnets, on the other hand, consist of coils of wire that gain a magnetic field when electricity is run through it, but lose it immediately when the electricity ceases.
When it comes to magnets bigger doesn’t necessarily always mean stronger. A lot of other factors determine a magnet’s strength, but size and shape should still be considered. For example, if you are making fridge magnets from heavy materials, strong disc shaped magnets that have a similar but slightly smaller surface area as the materials you are using are generally optimal.
