write lenzs law in electromagnetic induction? nd explain how it is based on conservation of energy? 5 marks jaldi kro plzzz
Answers
Explanation:
the ratio of sine of angle of incidence To sine of angle of refraction gives always constant is called snell's law
electromagnetic induction
Michael Faraday in English physicist is supposed to have studied in the generation of electric current using the magnetic field and Conducter
when a conductor is said to move inside a magnetic field and magnetic field is said to be changing around the field or a magnetic field is that to be changing around a conductor electric current is induced in the conductor this is just to opposite to the activation of a force by current carrying conductor in a magnetic field in other words when a conductor is brought in relative motion why Vizag a magnetic field and potential difference is induced in it this is known as electromagnetic induction

Answer:
Lenz's law is a common way to understand how electromagnetic circuits obey Newton's third law and the conservation of energy. Lenz's law is named after Heinrich Lenz, and it says: An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the change in original magnetic flux.
Lenz law states that the induced current always tends to oppose the cause which produce it. ... This extra work leads to periodic change in magnetic flux hence more current is induced. Thus the extra effort is just transformed into electrical energy which is law of conservation of energy.
