Find , the electromotive force (EMF) around a loop that is at distance from the axis,

a) Find \(\mathcal{E}(R, t)\), the electromotive force (EMF) around a loop that is at distance \(R\) from the \(z\) axis, where \(R\) is restricted to the region outside the iron rod as shown. Take the direction shown in the figure as positive. Express \(\mathcal{E}(R, t)\) in terms of \(A ,B_{0}, B_{1}, R,{\text {,and any needed constants such as }} \epsilon_{0}, \pi\), and \(\mu_{0}\) b) Due to the cylindrical symmetry of this problem, the induced electric field \(\vec{E}(R, t)\) can depend...

a)Find ε(R,t), the electromotive force (EMF) around a loop that is at distance R from the z axis, where R is restricted to the region outside the iron rod as shown. Take the direction shown in the figure as positive.Express ε(R,t) in terms of A, B0, B1, R, and any needed constants such as ,π, and μ0b)Due to the cylindrical symmetry of this problem, the induced electric field can depend only on the distance R from thez axis, where R is restricted to...

What is the difference between resting potential and repolarization? - Resting potential is maintained by leaky potassium channels. Repolarization occurs when potassium leaves the cell (and sodium channels are closed preventing sodium entry into the cell) causing the membrane potential to become more negative. - Resting potential is maintained by leaky potassium channels. Repolarization occurs when potassium enters the cell causing the membrane potential to become more negative. - Resting potential is maintained by potassium entry into the cell. Repolarization...
