yes lenz law states that every current opposes the reason which cause the generation of that current . it is very useful for considering back emf in dc motor.
The lenz law also help us to determine the supply voltage of DC motor.
Lenz's Law
LENZ LAW gives the direction of induced current.
If we use the simple application of Ohm's law where voltage (E) equals current (I) times resistance (R), or E = I x R, all we need to do is plug in values. If E = I x R and I = 8 amps and R = 15 ohms, E = 8 x 15 = 120 volts.
According to lenz law , "effect opposes the cause " now due to flux cutting action emf induce in coil opposes the flux by which this emf is induced . So this opposition by induced current of staring current is called inductance .
It's a practical example of the conservation of energy, and is explained by Lenz's Law. The direction of the load current is such that its magnetic field will create a force acting in the opposite direction to the force causing the conductor to move in the first place.
Lenz's Law is a part of Farady's Law known as the law of induction. It is a manifestation of the conservation of energy.
The Lenz Law is "An induced electromotive force generates a current that induces a counter magnetic field that opposes the magnetic field generating the current." It was invented by a Russian Physicist named Heinrich Lenz.
SCIENTIST: Heinrich Friedrich Emil Lenz
The Lenz's law equation is the same as the faraday equation but Lenz found a way to predict the direction of the induced electromotive force and current from electromagnetic induction. http://en.wikipedia.org/wiki/Lenz_law
Lenz's Law
Lenz's law and Faraday's law of Induction.The induced current causes a magnetic field according to Ampere's law, which itself has a flux through the closed loop. According to Lenz's law, the direction of the induced current and which results in the induced magnetic flux opposes the initial magnetic flux.
conversation of energy of electromagnetic
Lenz's law states that 'for a current induced in a conductor by a changing magnetic field, the current is in such a direction that its own magnetic field opposes the change that produced it.'
because its use formula from his father's law..
If Lenz's law were the opposite, the law of conservation of energy would be violated. Therefore, it is not reasonable to assume that it can be made to behave the opposite of what it does.
LENZ LAW gives the direction of induced current.
