[amp_mcq option1=”Maxwell’s right hand rule” option2=”Lenz’s rule” option3=”Flemings left hand rule” option4=”Kirchoff’s law” correct=”option3″]
The correct answer is C. Fleming’s left hand rule.
Maxwell’s right hand rule is used to determine the direction of the magnetic field around a current-carrying conductor. Lenz’s law states that the induced current in a circuit always opposes the change that causes it. Kirchhoff’s law is a set of two laws that are used to analyze electric circuits.
Fleming’s left hand rule is a mnemonic device used to determine the direction of the force on a current-carrying conductor in a magnetic field. The rule states that if you point your left thumb in the direction of the current, your fingers will curl in the direction of the force.
Here is a diagram that illustrates Fleming’s left hand rule:
The thumb represents the direction of the current, the index finger represents the direction of the magnetic field, and the middle finger represents the direction of the force.
I hope this helps!
