So it is true that the thickness of the wire affects the strength of the electromagnet. The strength of the magnet also increases as the wire thickness increases, since more electrons per unit area will pass through a thicker wire.
The four main factors affecting the strength of an electromagnet are the number of loops, current, wire size and the presence of an iron core.
There was one significant difference for this part of the experiment. My conclusion is that the thick core electromagnet is stronger than the thin core electromagnet. The wire size made no significant difference in the strength of the electromagnet.
Heavier wire means you can fit fewer turns in the same volume, which means less resistance and lower losses for the same amount of current, but less induced voltage, so thicker wire allows less voltage but more current.
The thin wire conducts electricity, but there is a higher electrical resistance. The thicker wire is like the four lane highway. There is much less electrical resistance and as a result the bulb burns brighter because more current can reach it.
So it’s true that the thickness of the wire affects the strength of the electromagnet. The strength of the magnet also increases as the wire thickness increases, since more electrons can pass through a thicker wire per unit area.
Factors that affect the strength of electromagnets include the type of core material, the amount of current flowing through the core, the number of turns of wire on the core, and the shape and size of the core.< /p>
Solid copper wire is better as it can usually carry more current. It’s best to have a large amount of copper to keep resistance low. It’s also good to have a lot of turns to make better use of the available current. Copper has the lowest resistance at room temperature, so it’s a good choice.
The larger diameter of the thicker wire gives more surface area for electrons to move through the circuit. For this reason, smaller gauge wires are rated for lower amperage limits than larger gauge wires.
Thicker is never worse than electrically thinner, but after a certain diameter, the extra area always gives you less and less. This effect is proportional to frequency, so a thicker cable is better for around 60Hz output than for a 10kHz signal to a speaker.
The relationship between resistance and wire length is proportional. The resistance of a thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current. The relationship between resistance and the area of a wire’s cross-section is inversely proportional.
Larger wires have less resistance and can transfer more power without much loss. Losses in smaller cables remain small if the transmitted power is small or the cable is not very long. Electric current and line resistance define the applicable voltage drop.
The longer a wire, the more resistance it has due to the longer distance electrons have to travel to get from one end to the other. The larger the cross-sectional area, the lower the resistance, since the electrons have a larger area to flow through. This is still true no matter how thick the wire is.
A thick wire (with a large cross-sectional area) has a lower resistance than a thin one* (with a small cross-sectional area). The resistance is inversely proportional to the cross-sectional area: R ∝ 1/A. This means that the larger the area, the less resistance.
The more wire you wrap around the nail, the stronger your electromagnet will be. Make sure you unwind enough wire to attach the battery. When wrapping the wire around the nail, make sure you wrap the wire in one direction.
The magnetic field of the current can act back on the magnet. For a magnet of given strength and size the interaction with the coil should decrease as the diameter of the coil increases (while keeping the number of turns constant).
Therefore, removing the iron core would also reduce the magnetic field strength.
The strongest electromagnet is therefore possible with a 5 cm coil with 200 turns.
