The magnetic losses in silicon steel under different core sizes can be influenced by several factors. Firstly, the size of the core itself is an important factor to consider. When the core size increases, the magnetic losses also tend to increase. This is because a larger core contains a greater volume of material, leading to higher eddy current losses. Eddy currents are induced in the core due to the changing magnetic field, resulting in energy losses in the form of heat. Therefore, a larger core size results in higher eddy current losses and consequently higher magnetic losses.
Another factor that affects magnetic losses is the thickness of the steel laminations used in the core. Thicker laminations generally have higher magnetic losses compared to thinner laminations. This is because thicker laminations offer less resistance to the flow of eddy currents, resulting in increased energy losses. On the other hand, thinner laminations increase the resistance to eddy current flow, thereby reducing magnetic losses.
The quality of the silicon steel used in the core also plays a significant role in determining magnetic losses. Silicon steel is specifically designed to have low magnetic losses by incorporating silicon in its composition to improve its magnetic properties. However, the quality of the silicon steel can vary depending on factors such as impurities or manufacturing processes. Lower-quality silicon steel may have higher magnetic losses compared to higher-quality silicon steel.
Additionally, the frequency of the alternating current flowing through the core can impact magnetic losses. At higher frequencies, the magnetic losses tend to increase due to the skin effect. The skin effect causes the alternating current to concentrate near the surface of the core, resulting in increased eddy current losses.
Lastly, the design of the core, including its shape and geometry, can influence magnetic losses. Different core shapes and geometries can have varying effects on the distribution of magnetic flux and eddy currents, thereby affecting the overall magnetic losses.
In conclusion, the factors that influence magnetic losses in silicon steel under different core sizes include the core size, thickness of the steel laminations, quality of the silicon steel, frequency of the alternating current, and the design of the core. Understanding and considering these factors is essential for optimizing the performance and efficiency of magnetic devices that utilize silicon steel cores.

The factors influencing the magnetic losses in silicon steel under different core sizes include the hysteresis losses, eddy current losses, and excess losses. Hysteresis losses occur due to the energy dissipated during the magnetization and demagnetization cycles of the material. Eddy current losses arise from the circulating currents induced by the changing magnetic field, leading to resistive heating. Excess losses are caused by factors such as the quality of the material, manufacturing processes, and core geometry. These losses increase with larger core sizes due to the increased volume of material and longer magnetic paths, resulting in higher energy dissipation and eddy currents.
