Is there some thing really called left-hand rule? I have heard my teacher say it but she is not reliable. I have heard of right hand rule(RHR)? Or is it imporsonation of RHR to go with flow of electron instead of protons

Fleming's left hand rule, for working out the force effect of a
current and field. Using your left hand, first finger points at the direction of the field, second finger the conventional current, and thumb gives direction of force.
No, the Left-hand Rule is not inherently unreliable. It is a commonly used tool in science, particularly in physics, and has been found to be accurate in many situations.
The Left-hand Rule is used to determine the direction of a magnetic field when a current is flowing through a wire. It can also be used to determine the direction of the force on a current-carrying wire in a magnetic field.
Yes, the Left-hand Rule may not be applicable in all situations, particularly when dealing with non-uniform magnetic fields or complex wire configurations. It is also based on the assumption of a uniform magnetic field, which may not always be the case.
The Left-hand Rule is used for determining the direction of a magnetic field or the force on a current-carrying wire, while the Right-hand Rule is used for determining the direction of a magnetic force on a moving charged particle.
There may be confusion surrounding the Left-hand Rule due to its multiple variations and different applications. Additionally, it is possible that some may misinterpret or misuse the rule, leading to incorrect results.
