Question

1) Right hard thumb rule
2) Fleming's left hand rule
3) Faraday's law of Induction​

Answer 1

Answer:

• The right-hand rule imposes the following procedure for choosing one of the two directions. With the thumb, index, and middle fingers at right angles to each other (with the index finger pointed straight), the middle finger points in the direction of c when the thumb represents a and the index finger represents

• Faraday's law of induction is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force —a phenomenon known as electromagnetic induction. Wikipedia
• Formula
• \varepsilon=-N \frac{\Delta \Phi}{\Delta t}
• \varepsilon = induced voltage
• N = number of loops
• {\Delta \Phi} = change in magnetic flux
• {\Delta t} = change in time

The right hand rule used to find the direction of magnetic field due to current element is as follows:

Right hand rule states that, if the thumb of the right hand is in the direction of the current flow then, the curl fingers show the direction of the magnetic field.

Fleming's left-hand rule states that “When a current-carrying conductor is placed in an external magnetic field, the conductor experiences a force perpendicular to both the field and to the direction of the current flow.”

Michael Faraday’s famous law of electromagnetic induction states: “that a voltage is induced in a circuit whenever relative motion exists between a conductor and a magnetic field and that the magnitude of this voltage is proportional to the rate of change of the flux”.
