The voltage, orelectromotive force(emf), that results from the behavior of an electromagnet needs to be accounted for through techniques in physics and engineering to keep yourself and others safe. The current that flows through an electromagnet dictates how strong it is and, therefore, what sort...
According to the Nernst equation, the electrode potential shift (ΔEM/Mn+) is linked to the activities of the chemical species involved in the half-cell reactions. ΔEM/Mn+ = RTnFlnaMn+ for Mn++ne=M. where R, T, n, F, and aMn+ denote the gas constant, absolute temperature, nu...
