The power of the battery controlling it.
longer= stronger
It's directly proportional.
yes,the more the coils the more the strength it collects
One of them is how many coils go around the electromagnet. also the amout of current flow< and the type of core material.
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.

The more turns of wire in an electromagnet the stronger the magnetic field.

An electromagnet becomes stronger when the current through it increases, i.e. the Amps.
The strength of an electromagnet is determined by the density of coils surrounding the magnet, and the rate of current passing through those coils.
This is because an electromagnet gets its magnetic force from the electrons passing through the wire, the more coils there are the more electrons passing through so the more magnetic power. Obviously this only works to an extent since you would need more voltage and so on.
an electromagnet requires electricity and you will have to pay for it. permanent magnets are always on and you can change the strength of it.
