Which rule is used in electromagnetic induction?
Fleming’s left hand rule is used for finding the directions of the motion for electric motors while Fleming’s right hand rule is used for finding the direction of the induced current in electric generators.
What is Fleming right hand rule Class 10?
Fleming’s right hand rule can be stated as: Stretch the forefinger, the middle finger and the thumb of the right hand, such that they are mutually perpendicular to each other.
What are the two laws of electromagnetic induction?
First law: Whenever a conductor is placed in a varying magnetic field, EMF induces and this emf is called an induced emf and if the conductor is a closed circuit than the induced current flows through it. Second law: The magnitude of the induced EMF is equal to the rate of change of flux linkages.
Which law gives the direction of induced emf?
Lenz’s law gives the direction of induced emf with respect to the change in magnetic flux but Fleming’s law gives the direction of induced emf more accurately.
Is right hand rule for electrons or protons?
In both hand rules, the thumb represents current, first finger is field and the second finger is the force. The right hand rule is for conventional (hole) current, and the thumb represents the direction of hole current. The left hand rule is for electron current, and the thumb represents the electron current.
What is Fleming right hand Rule 12?
According to Fleming’s right hand rule if we stretch 3 fingers of our right hand, then the :- Thumb will point to the motion of the conductor. First Finger points towards the magnetic field. Middle finger points to direction of the induced current.
What is Fleming right hand rule Brainly?
Fleming’s right hand rule states that if we hold the forefinger, middle finger and thumb of right hand mutually perpendicular to each other, then the forefinger points in the direction of external magnetic field and thumb points in the direction of motion of conductor.
How do you use Flemings right hand rule?
“Hold the right-hand forefinger, middle finger and the thumb at right angles to each other. If the forefinger represents the direction of the magnetic field, the thumb points in the direction of motion or applied force, then the middle finger points in the direction of the induced current.”
What is the first law of electromagnetic induction?
Faraday’s first law of electromagnetic induction states that “Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. Likewise, if the conductor circuit is closed, a current is induced, which is called induced current.”
What is Faraday 2nd law?
Faraday’s second law of electrolysis states that ”The masses of different ions liberated at the electrodes, when the same amount of electricity is passed through different electrolytes are directly proportional to their chemical equivalents”.
What is Faraday’s 1st and 2nd law?
The first law states that the amount of chemical change being produced by a current at an electrode-electrolyte interface is proportional to the quantity of electricity used while the second one tells that the amounts of chemical changes produced by the same quantity of electricity in different substances are …
