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 $1.8 \times 10^{-5} \mathrm{~T}$. WebElectrostatic induction is a method to create or generate static electricity in a material by bringing an electrically charged object near it. This causes the electrical charges to be redistributed in the material, resulting in one side having an excess of either positive (+) or negative (−) charges. WebIt is also called as coefficient of mutual induction. If i1 =1A , then M 21 = N2 Φ 21 . Therefore, the mutual inductance M21 is defined as the flux linkage of the coil 2 when 1A current flows through coil 1. When the current i1 changes with time, an emf ε2 is induced in coil 2. From Faraday’s law of electromagnetic induction, this mutually ... ibm rehire
