When an induced current is generated by a change in magnetic flux, as stated by Farady's Law, the induced current will flow creating its own magnetic field that opposes the magnetic field that created it.

==The Main Idea==

Lenz's Law makes sure that Faraday's Law follows the conservation of energy as stated by Newton's Third Law. According to Faraday's Law, any change a the magnetic field will cause an induced current (emf). Lenz's Law accounts for the direction of the induced current. The change can be caused by the strength of the magnetic field, the direction of the magnetic field, the position of a circuit, the shape of a circuit, or the orientation of a circuit. The induced magnetic field inside a loop of wires is created to keep the magnetic flux in the loop constant.

===A Mathematical Model===

Lenz's Law is mathematically modeled as part of Faraday's Law. The negative sign in the equation represents the opposing induced field.
<math>\epsilon = -{\frac{d\phi}{dt}} </math> where '''<math>\epsilon</math>''' is the emf of the system and '''<math>d\phi</math>''' is the change in the magnetic field.

==Examples==

Use the right hand rule to find the non-coulombic electric field in the given situations.
[[File:Non-Coulobmic_Fields.gif]]

===Solution===

To use the right hand rule: place your thumb in the direction of the <math> -dB </math>, then curl your fingers. The direction in which your fingers curl is the direction of the non-coulombic electric field. The non-coulombic field is represented by the pink arrows.

==Connectedness==
An interesting application for Lenz's Law is to cause rotation to create energy. In an industry setting, Lenz's Law can be applied to electric generators or electric motors. When a current is induced in a generator, the direction of the induced current will flow in opposition of the magnetic field that created it, causing rotation of the generator. And so, the generator needs more mechanical energy.

==History==

Henrich Friefrich Emil Lenz (1804-1865), a Russian physicist of German origin was born in Dorpat, nowadays Tartu, Estonia. Henrich studied chemistry and physics at the University of Dorpat in 1820 after his secondary education. From 1823 to 1826, he traveled with the navigator, Otto von Kotzebue on his third expedition around the world. During this journey he studied climate conditions, and properties of seawater. After his travels, he worked at the University of St. Petersburg, Russia, where he later became the Dean of Mathematics and Physics from 1840 to 1863. In the year of 1831, he started studying electromagnetism, and soon after in 1835, what is known today as Lenz's Law was created. Lenz died on February 10, 1865, just two days before his 61st birthday, after suffering a stroke, while in Rome.

Since Lenz's Law and Farady's Law go hand in hand, Faraday's Law would be great supplemental information to read about. Newton's Third Law would also be a topic to read on for further understanding why Lenz's Law exists.

<math>\epsilon = -{\frac{d\phi}{dt}} </math> where '''<math>\epsilon</math>''' is the emf of the system and '''<math>d\phi</math>''' is the change in the magnetic field.

==History==

Henrich Friefrich Emil Lenz (1804-1865), a Russian physicist of German origin was born in Dorpat, nowadays Tartu, Estonia. Henrich studied chemistry and physics at the University of Dorpat in 1820 after his secondary education. From 1823 to 1826, he traveled with the navigator, Otto von Kotzebue on his third expedition around the world. During this journey he studied climate conditions, and properties of seawater. After his travels, he worked at the University of St. Petersburg, Russia, where he later became the Dean of Mathematics and Physics from 1840 to 1863. In the year of 1831, he started studying electromagnetism, and soon after in 1835, what is known today as Lenz's Law was created. Lenz died on February 10, 1865, just two days before his 61st birthday, after suffering a stroke, while in Rome.

Since Lenz's Law and Farady's Law go hand in hand, Faraday's Law would be great supplemental information to read about. Newton's Third Law would also be a topic to read on for further understanding why Lenz's Law exists.

===Collisions===
<div class="mw-collapsible-content">
*[[Collisions]]
Collisions are events that happen very frequently in our day-to-day world. In the realm of Physics, a collision is defined as any sort of process in which before and after a short time interval there is little interaction, but during that short time interval there are large interactions. When looking at collisions, it is first important to understand two very important principles: the Momentum Principle and the Energy Principle. Both principles serve use when talking of collisions because they provide a way in which to analyze these collisions. Collisions themselves can be categorized into 3 main different types: elastic collisions, inelastic collisions, maximally inelastic collisions. All 3 collisions will get touched on in more detail further on.
*[[Elastic Collisions]]
A collision is deemed "elastic" when the internal energy of the objects in the system does not change (in other words, change in internal energy equals 0). Because in an elastic collision no kinetic energy is converted over to internal energy, in any elastic collision Kfinal always equals Kinitial.
*[[Inelastic Collisions]]
A collision is said to be "inelastic" when it is not elastic; therefore, an inelastic collision is an interaction in which some change in internal energy occurs between the colliding objects (in other words, change in internal energy does not equal 0). Examples of such changes that occur between colliding objects include, but are not limited to, things like they get hot, or they vibrate/rotate, or they deform. Because some of the kinetic energy is converted to internal energy during an inelastic collision, Kfinal does not equal Kinitial.
