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.

How are electro magnets different from other magnets?
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.
Is larger magnets always stronger than small magnets?
no
How are electro magnet different from permanent magnet?
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.
Are artificial magnets stronger than natural?
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.
Are bar magnets stronger than electro magnets?
Yes, because electromagnets can lose their magnetism.
Which magnets can retain their property for a short period of time?
Electro-magnets
Do magnets repel non magnetic materials not including electro-magnets?
of course not.

Why are magnets used?
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.
Is gravity getting weaker Or is electro-magnetism getting stronger Or both?
Electro-magnetism gets stronger.
Are electro magnets sometimes called artificial magnets?
Yes, electromagnets itself is an artificial magnet.
Are colder magnets stronger then hot magnets?
yes

What supply should be given for making electro magnets... ac or dc?
For a simple electro-magnet use a DC supply.
What has electro magnets in them?
Lots of things do. For example, relays. (The electronical component)
Does stacking magnets make them stronger?
No, stacking magnets does not make them stronger. Magnets have a set strength based on their material and size, and stacking them does not increase this strength.
