The Strength of an Electromagnet

Introduction of the strength of the electromagnet: [Image] Current flowing through the wire generates a magnetic field. When winding the wire, a stronger magnetic field is generated. Winding it on a soft iron core increases the strength effect; increasing the number of currents or coils is further increased. Let's investigate the increase in current and the influence on the electromagnet. The electromagnet will generate a stronger magnetic field and pick up more iron filler.

The purpose of this project is to plan and execute a simple, fair, controlled and safe experiment to determine factors controlling the strength of the electromagnet. I learned from previous research that the strength of an electromagnet depends on the number of coils used, the amount of current supplied to the wire, and the strength of the wire by placing iron or steel in the center of the coil. My strength has increased. In this project, we will study patterns that change the amount of current flowing through the coil changing the strength of the electromagnet.

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.
