You can change the strength of an electromagnet 3 ways. You can increase the amount of current (Amperes) running through your wire. You can increase the number of turns, or, if insulated, number of layers of turns on your wire coil. Last you can change the core - material, density, diameter, length.

Electromagnets use electricity to create a magnetic field, which can be turned on and off. They are typically stronger than permanent magnets. In contrast, permanent magnets, like those made of iron or nickel, are always magnetic without the need for an external power source.

Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
Artificial magnets can be stronger than natural magnets. This is because they are engineered using specific materials and manufacturing processes that optimize their magnetic properties. For example, neodymium magnets, a type of artificial magnet, exhibit significantly higher magnetic strength compared to most natural magnets like lodestone. Therefore, in many applications, artificial magnets are preferred due to their superior strength and performance.
Yes, because electromagnets can lose their magnetism.
Electro-magnets
of course not.

Electro magnets can be very useful to carry heavy loads of iron and metal from one side of a factory to another. Electro-magnets are formed by shooting electricity through a coil of copper.
Electro-magnetism gets stronger.
Yes, electromagnets itself is an artificial magnet.

For a simple electro-magnet use a DC supply.
