WebWhat is flux in transformer? In a transformer, the magnetic flux created by the primary coil induces a current in the core. This occurs in order to oppose the charge that produced the magnetic flux (Lenz's Law). The currents flowing in the core are called eddy currents. These currents produce heat, using up energy and so causing inefficiency. WebAug 14, 2024 · The formula method uses the fundamental transformer equation to calculate the effective flux density for a particular value of fault current. The calculated flux density is then compared to the capability of the steel used in the core of the CT and a determination is made whether the core will saturate or not for that fault current.

WebWorked example An aluminium window frame has a width of $40 \mathrm{~cm}$ and length of $73 \mathrm{~cm}$ as shown in the diagram below. The frame is hinged along the vertical edge AC. When the window is closed, the frame is normal to the Earth’s magnetic field with magnetic flux density $1.8 \times 10^{-5} \mathrm{~T}$. WebFlux per unit of cross-sectional area is called flux density. Magnetic Flux Density Formula Its letter symbol is B. The relationship between total flux and flux density is given by the following equation: B = φ A B = φ A Where B=flux density in Tesla φ=total magnetic flux in weber A= Cross-sectional area in square meter Magnetic Flux Density Unit “shark tank update” fat shack
