Helix Left Handed Ruler,Blue,30cm

Product Information

This rule states, “If you stretch your right hand with the forefinger, middle finger and thumb at the right angle to each other such that the forefinger points in the direction of force, the thumb points in the direction of motion or applied force, then middle finger points will give the direction of the induced current.”

Left-handed scissors are now commonplace in schools. As are many other tailored items including left-handed notebooks, can openers and computer mice. Perhaps arguably one of the most commonly used items in both business and education is the ruler and left-handed rulers have become more and more common in the market. Why choose a left-handed ruler? The direction of current will be along with east, i.e. in the direction of motion of proton. Applying Fleming’s left-hand rule, the force experienced by the proton will be along the north.The direction of the current will be along the direction of the motion of the alpha particle. So, the direction of the current is towards the west. According to Fleming’s Left-Hand Rule, the middle finger shows the current direction, the forefinger shows the direction of the magnetic field, and the thumb shows the direction of motion. Applying this rule, the direction of the magnetic field would be upwards. Summary The comparison between Fleming’s Right Hand Rule and Left Hand Rule will help students differentiate between these concepts with utmost clarity. The difference between these concepts is stated as follows: Left Hand Rule

Especially in the world of rulers in the modern world, we are taught to read from left to right. Now consider how cumbersome it can be trying to take measurements as a left-handed person on a tool that measures from left-to-right. Where do you put your hand? How do you hold the ruler steadily? We are given that an electron is moving upwards, and an external magnetic field is acting on it along the east direction. Our left-handed rulers are no exception. So improve the productivity of your day while benefitting from a ruler that has been tailored to meet your exact needs.

We are given that a proton is moving towards the east, and a magnetic field is acting on it in the downward direction. Electric motor: One of the most common and well-known applications of Fleming’s left-hand rule can be seen in the working of an electric motor. Let us try to understand how an electric motor works: We know, When a current-carrying conductor comes under a magnetic field, there will naturally be a force acting on the conductor. Fleming’s Left-Hand Rule is a simple and accurate way to find the conductor’s direction of force/motion in an electric motor when the magnetic field direction and the current direction are known. The thumb, forefinger, and middle finger of the left hand are stretched in a perpendicular direction with respect to each other such that:

As any 'leftie' will know, working with the wrong tools throws up a host of individual issues. Many times, right-handed tools are uncomfortable to hold. In other situations, it comes down to comfort. John Ambrose Fleming in the late \(19 Left-handed rulers respond to this need, particularly our 12"/30cm Clear Plastic Left-Handed Ruler. The perfect tool for any environment, it has the numerical markers printed from right to left instead. After a few practise sessions, you'll be taking measurements like a pro, without worrying about where to lean or place your arm. Do I need a left-handed ruler?Whatever the reason may be, it is estimated that approximately of people in the world are left-handed. Therefore, this significant group deserves access to tools designed for their needs. If you're left-handed, or indeed even if you're not, it isn't hard to notice the simple tasks in like that can become much more difficult without the right resources.
