![]() The direction of the induced EMF is such that it opposes the cause which produces it, which means it opposes the change of current in the first coil. This phenomenon was proposed by Lenz, and it is called Lenz’s Law. In other words, the direction of the EMF produced in coil-2 opposes the current in coil-1. The direction of induced EMF always opposes the reason for its production. The EMF produced in coil-2 is called Mutually Induced EMF. A galvanometer connected in coil-2 measures the induced EMF. This changing flux links to coil-2 and produces EMF. The magnitude of electric current changes with a change in the value of the resistance and it leads to a change in the flux in the coil-1. The change in the current can be done through the variable resistor (R). The change in the flux in coil-1 happens when the current changes. we assume, that most of the flux says φ 12 links with the other coil-2. The flux produced in coil-1 links to coil-2. On closing the switch (S) in the circuit shown above, the current I 1 flows through the coil -1, and it produces the fluxφ 1. We can understand the mutually induced phenomenon by taking the following example. The transformer functions on the principle of mutual induction. There is a wide application of mutually induced EMF. In addition, the electric force plays an essential role in maintaining the structure of matter, by keeping the nucleus of the atom together, and by preventing electrically neutral atoms from collapsing into each other.Mutually Induced EMF is the EMF induced in a coil caused by the change of flux produced by another neighboring coil linking to it. The electric force is also responsible for the phenomenon of electricity, including lightning, static electricity, and the flow of electrical current in a conductor such as a wire. The electric force is responsible for maintaining the cohesion of atoms and molecules, and keeping atoms and molecules together, even though electrically neutral atoms tend to repel each other. The electric force is carried by elementary particles called electrons, protons and neutrons. The electric force is one of the four fundamental forces (the others are the strong force, the weak force, and gravity) of nature, and is responsible for a wide range of phenomena, such as the interactions between the components of atoms and molecules, and the formation of molecular bonds and chemical compounds. The electric force plays a major role in determining the internal properties of most objects encountered in daily life. The electric force is a physical force exerted by electrically charged particles, and is the force responsible for a number of phenomena in electromagnetism. ![]()
