fleming's left hand rule relations of increase and decreaseand reverse, etc. all

Fleming's left hand rule is a concept used in physics to determine the direction of a force acting on a current-carrying conductor in a magnetic field. It is based on the relationship between the direction of the current, the magnetic field, and the resulting force.

To understand the relations of increase and decrease, as well as the reverse, according to Fleming's left hand rule, follow these steps:

1. Extend your left hand and stretch out your thumb, index finger, and middle finger perpendicular to each other.
2. Align your thumb with the direction of the force (F) acting on the conductor.
3. Point your index finger in the direction of the magnetic field (B).
4. Your middle finger will then indicate the direction of the current (I) flowing through the conductor.

Now, let's discuss the relations:

• Increase: If you increase the current (I) or the magnetic field (B), the force (F) acting on the conductor will also increase. This means that if you curl your fingers towards your palm, the force (F) will be in the direction indicated by your thumb.
• Decrease: Conversely, if you decrease the current (I) or the magnetic field (B), the force (F) acting on the conductor will decrease. In this case, if you uncurl your fingers, the force (F) will be in the opposite direction indicated by your thumb.
• Reverse: If you reverse the direction of either the current (I) or the magnetic field (B), the force (F) acting on the conductor will also reverse. To determine the new direction, simply reverse the orientation of your hand and follow the same steps as before.

Remember, Fleming's left hand rule is a useful tool for understanding the relationship between current, magnetic fields, and forces in a conductor.
