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 solendoids related to electro magnets?

Iron better than steel in electro magnets?
Yes, they are.
How are electro magnets different from other magnets?
An electromagnet can be turned on and off, with an electric current and a magnet can not turn off
Is larger magnets always stronger than small magnets?
no
Does the thickness or length of the nail affect the electro magnets strength?
yes
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
How does heat make a magnet stronger?
It doesnt. Heat makes magnets weaker while cold will make them stronger.
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.
Iron better than steel in electro magnets?
Yes, they are.
Are colder magnets stronger then hot magnets?
yes
