That's because the strenght of the electromagnet is related to the number of coils then, the more coils gets more strenght because as you add more coils to the electromagnet you have more and more magnetic field.
-I hope this answer helps you if you have a question regarding any questions on any subject please fell free to ask. Thank You
The strength of the magnetic field in an electromagnet is influenced by factors such as the number of coils in the wire, the amount of electric current flowing through the wire, the material of the core inside the coil, and the shape and size of the electromagnet. Increasing any of these factors typically increases the strength of the magnetic field produced.
The strength of an electromagnet is directly proportional to the current flowing through the coil. Increasing the current in the coil increases the magnetic field strength produced by the electromagnet. This means that increasing the size of the current in the coil will make the electromagnet stronger.
The size and length of the metal core can affect the strength of an electromagnet. A longer core will generally result in a stronger magnetic field, but the material and diameter also play a role. The core should be made of ferromagnetic material like iron or steel for best results.
Factors such as the number of turns in the coil, the amount of current flowing through the coil, the material of the core inside the coil, and the presence of any ferromagnetic materials nearby can affect the strength of an electromagnet. Additionally, the size and shape of the coil, as well as the distance between the coil and the object being attracted, can also impact the magnet's strength.
The strength of an electromagnet is directly proportional to the current passing through the coil. Increasing the current will increase the strength of the magnetic field produced by the electromagnet, whereas decreasing the current will weaken the magnetic field.

An electromagnet can be very strong, with some industrial electromagnets capable of lifting thousands of pounds. The strength of an electromagnet depends on factors such as the number of coils of wire, the current running through the coils, the type of core material used, and the size and shape of the electromagnet.
The strength of an electromagnets magnetic field depends on:The type of core metalThe ability of the wire to carry current (its material and thickness)The number of turns of the wiring around the coreThe voltage/current of the electricity going through the wire.
It can. If the core isn't large enough for the number of windings and the amount of current flowing through those windings, the field can saturate the core. If the core is saturated, driving more current through the windings to increase the field strength will fail to achieve that increased field strength. The current is "wasted" that way. Let's look at saturation first. Picture a horseshoe for our core shape. When direct current flows through the windings in an electromagnet, it sets up a magnetic field in the core. (The windings are wound around the core like fishing line on a fishing reel.) The lines of force go through the core material, and, since we are using a horseshoe magnet, the lines of force will travel all the way though the core and will "emerge" from one end of the horseshoe to "jump the gap" across the open end of the magnet to "get back into" the other pole. That way the magnetic field can have a "closed circuit" from the point of view of the magnetic lines of force. Magnets will always have lines of force emerging from one pole and taking some path to get to the other pole to go back into the core. And just like a pipe can allow only so much water to flow through it because of its size, the same can be said to be true with the core of an electromagnet. There is a limt as regards the number of magnetic lines of force that can pass through a core of a given size (material considerations aside). Only so many of the lines of force can pass through before saturation occurs and no more can be included. That's a function of the size of the core (as well as a couple of other factors). A bigger core will allow us to increase the lifting capacity when we increase the current in the windings. That way we can avoid saturating the core. Let's pretend we have an electromagnet that will lift, say, a ton, and it uses, say 100 amps of DC current to do that. We want to lift a ton and a half, so we try to drive 150 amps through the windings. But let's say that the core saturates at 110 amps. That means that the core won't support more magnetic lines of force than will be flowing when the current is at 110 amps. We can continue to drive more current through the windings in the electromagnet, but the lifting power won't continue to increase. The saturated core has limited the amount of weight we can get the electromagnet to lift. The core is too small to work at the elevated current we want it to work at. Electromagnets are usually designed with a specific load limit in mind. It is possible to "overdrive" the electromagnet a bit to increase load capacity, but there will be a limit to what can be done to make the magnet pick up a heavier load. The size of the core is one of the factors that will limit the capacity of the electromagnet.
The number of turns in the coil of an electromagnet affects its strength. More turns generally result in a stronger magnetic field because each turn contributes to the overall magnetic flux. Increasing the number of turns increases the magnetic field intensity and thus the strength of the electromagnet.
Size does not but mass does.
First off, the two main factors are the power source and the number of windings in your Electromagnet. Higher wattage input can produce a stronger magnetic field. More windings will also increase the strength of the field. Type and gauge of the conductor will also affect performance. More factors to consider: The diameter of the coils, and the inductor core material. Make a simple ring of wire, maybe a dozen windings, attach a power source, and you will have an electromagnet (though not very useful in that form). Wrapping a wire around a large iron nail and attaching a power source will prove more effective. In the first example the core material is natural air. Air does not induce well, and therefore does not create a good magnet. In the second example, the iron core (the nail) through induction, greatly increases the magnetic field. The iron can also become temporarly magnetized through this process. Note: Do NOT use household line voltage, as this may be too powerful and cause injury.
The study likely tested how the size of the nail (diameter, length) affects the electromagnet's strength. This could demonstrate how changes in the core material impact magnetic properties. The number of paper clips picked up would increase with a larger or more magnetic core, showing a proportional relationship.
