  • Faraday’s Laws of Electromagnetic Induction
    Faraday’s First Law of Electromagnetic Induction The discovery and understanding of electromagnetic induction are based on a long series of experiments carried out by Faraday and Henry From the experimental observations, Faraday concluded that an emf is induced when the magnetic flux across the coil changes with time Therefore, Faraday’s first law of electromagnetic induction states the
  • Spontaneous Mutation - BYJUS
    Oxidative damage (Reactive oxygen species, e g superoxide radical, hydrogen peroxide) Ionising and non-ionising radiations (gamma radiations, ultraviolet radiations, X-rays, etc ) Difference between Spontaneous and Induced Mutation The table below shows the main differences between Spontaneous and Induced Mutation
  • Formula of Induced Voltage - BYJUS
    ε is the induced voltage N is the t otal number of turns of the loop = B A B is the magnetic field A is the area of the loop t is the time Induced Voltage Solved Example Problem 1: Consider a rectangular coil of 5 turns with a side length of 0 5 m This coil reaches the magnetic field 0 3T within 10s Compute the induced voltage? Answer:
  • What is Induced EMF? - BYJUS
    Question What is Induced EMF? Solution Induced EMF Induced EMF: I f the magnetic flux through a coil is changed, a voltage will be produced This voltage is known as the induced emf Induced EMF can be created in two ways: If an electric current conductor moves in a magnetic field then an induced emf is produced
  • What is Inductance? - BYJUS
    What is Inductance? Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it L is used to represent the inductance, and Henry is the SI unit of inductance 1 Henry is defined as the amount of inductance required to produce an emf of 1 volt in a conductor when the current change in the conductor is at the rate of 1 Ampere per second
  • What Is Electromagnetic Induction? - BYJUS
    Applications of Electromagnetic Induction Based on his experiments we now have Faraday’s law according to which the amount of voltage induced in a coil is proportional to the number of turns of the coil and the rate of changing magnetic field AC generators work on the principle of electromagnetic induction The working of electrical transformers are based on electromagnetic induction The
  • What is an Induced Electromotive Force? - BYJUS
    The induced magnetization in the string is picked up from the vibration of the guitar The input of an amplifier of the guitar is connected to the two ends of the coil which are connected to the speakers Stay tuned with BYJU’S to learn more about emf, induced electromotive force, and much more
  • Law of Magnetic Induction - BYJUS
    Law of Magnetic Induction Magnetic induction, also called electromagnetic induction refers to the production of voltage (or EMF) across an electrical conductor placed inside a varying magnetic field According to Faraday’s law, for a closed circuit, the induced electromotive force is equal to the rate of change of the magnetic flux enclosed by the circuit To know more about magnetic
  • What are Intermolecular Forces? - BYJUS
    4 Dipole Induced Dipole Interaction These interactions are similar to ion-induced dipole interactions However, the differentiating factor is that non-polar molecules are transformed into induced dipoles due to the presence of a polar molecule nearby 5 Dispersion Forces or London Forces It operates for a short distance and it is the weakest
  • What is Dipole Moment? - BYJUS
    What is Dipole Moment? A dipole moment arises in any system in which there is a separation of charge They can, therefore, arise in ionic bonds as well as in covalent bonds Dipole moments occur due to the difference in electronegativity between two chemically bonded atoms Table of Contents Important Points on Dipole Moment Recommended Videos Dipole Moment Formula Examples Dipole moment of
