A consistent magnetic field positioning openly up is gradually switched on, so the magnetic field strength can be expressed like a time function as B(t) = 0.02(T /s2) ×t2. A circular shape wire coil including 350 turns & a 7.5 cm radius is located horizontally over a table. To generate an induced current, the magnetic field uses a force over the coil, and in sequence, a force is used through the current supply on the magnetic field to restrict it. So, based on Lenz’s law, the coil’s motion is restricted once the induced current is provided within a similar direction. In this 3rd experiment, Lenz stated that once the coil is dragged in the direction of the magnetic flux, then the coil which is associated through it decreases. In this 2nd experiment, Lenz declared that once the current-carrying coil is wounded over an iron rod using his left end which acts like an N-pole & is turned toward the ‘S’ coil, then an induced current will be generated. So, the induced current flow direction will restrict once the magnetic flux enhances. When the current supply within the coil increases, the magnetic flux will be increased. In this experiment, Emil Lenz said that when the current flows within the coil of the circuit then generate magnetic field lines. For this law, the following three experiments were proved through his theory. This Lenz’s law experiment is mainly for discovering the induced electromotive force direction & current we look for Lenz’s law. If the induced current forms a magnetic field that is equivalent and reverse to the magnetic field’s direction that makes it, then only it resists the magnetic field change within the region. This law generally obeys Newton’s 3rd law of motion, which states that for each action there is always an equivalent and reverse reaction. Thus, we can conclude that if Lenz’s law did not state that the induced current should form a magnetic field to restrict the created field, then we would finish up with a nonstop positive feedback loop for breaking the protection of energy. This magnetic field will induce one more current in the conductor to twice the induced current’s magnitude. Once the magnetic field formed through the current induced will be in a similar direction like the field generated it, after that these magnetic fields would merge to make a bigger magnetic field. This law is an outcome of the energy conservation law. The induced current direction through Lenz’s law must generate a magnetic field to obey the energy conservation that restricts the magnetic field that produced it. In Faraday’s law of electromagnetic induction, the negative sign mainly specifies the induced EMF or ε & the change within magnetic flux or δΦB has reverse signs. Here, an induced current can be generated through the induced EMF’s polarity where the magnetic field restricts the primary changing magnetic field. Thus, we can say that the electromagnetic field’s magnitude which is induced within the circuit is proportional to the change rate of flux.Īccording to Faraday’s Law, when an emf is produced through a change within magnetic flux is known as Lenz’s law. The magnetic field can be adjusted by changing its field’s strength or by moving the magnet in the coil direction or moving away from the coil, etc. Thus, this is denoted in Faraday’s law formula through the negative sign. Lenz’s law mainly depends on Faraday’s law of electromagnetic Induction because Faraday’s law states that a varying magnetic field will induce a flow of current within an electric conductor while Lenz’s law states that the induced current direction which restricts the early changing magnetic field which generated it. So, this field will be restricted through the magnetic field that formed it. Once a current is induced through a magnetic field, then the magnetic field generated through the induced current will form its magnetic field.
