The Effect of the Number of Coils on an Electromagnet On Its Strength

Influence of the number of coils on the strength of the electromagnet Purpose: - Determine whether changes in the number of coils will affect the strength of the electromagnet. Scientific knowledge: - The concept of electromagnet is very simple. When wound with a series of insulating coils and then attached to the battery, the nail can pick up the paper clip. This is because the current flowing from the battery to the coil magnetizes the nail. This is called an electromagnet.

F1: As you can see, the chart is proportional. As the number of coils increases, the strength of the electromagnet also increases. There is a positive correlation, which is also proved by theory. As the number of coils increases, the magnetic field of each coil also increases, so the electromagnet becomes stronger as the magnetic field increases. There are only one exception in the results of 20 coils, but this is a negligible exception and can be ignored. F2: In this figure, I also noticed that there is a positive common relationship, so the current is proportional to the strength of the magnet. As the current in the circuit increases, as the coil is charged more, the strength of the magnet also increases, so the field lines spread over a larger area and the intensity becomes larger. However, in the chart after 0 amperes, the chart is no longer proportional

Our chart shows our assumptions about these two factors. The strength of the electromagnet is proportional to the current in the solenoid and the number of coils. As the number of coils increases, the area of ​​magnetic force lines also increases, so a more powerful electromagnet is generated. The current increase is the same. However, after a constant current, it is difficult to maintain other constant factors such as temperature, which can lead to inaccurate results.

From my chart, increasing the number of coils shows that the electromagnet picks up more nails. This means that as the number of coils increases, the strength of the electromagnet increases. My graph can tell me that there is a steady increase, and my results table will tell me this. My average result is steadily increasing every time the number of coils increases. You can see that there are ten coils around the core, only three nails are picked up, 100 coils are wound around the core, and 20 nails are picked up. There is a significant increase here.
