What is the left hand rule for magnetism and how is it used to determine the direction of the magnetic field in a current-carrying conductor?
The left-hand rule for magnetism is a way to determine the direction of the magnetic field around a current-carrying conductor. To use this rule, point your thumb in the direction of the current flow (from positive to negative), your index finger in the direction of the magnetic field, and your middle finger will then point in the direction of the magnetic field lines. This rule helps to visualize and understand the relationship between current flow and magnetic fields in a conductor.
To use your left hand to determine the direction of the voltage developed in moving conductor in a stationary magnetic field you must point your?
forefinger in the direction of the lines of force
What is the left hand rule of electromagnetism and how is it used to determine the direction of the magnetic field created by a current-carrying conductor?
The left-hand rule of electromagnetism is a rule used to determine the direction of the magnetic field created by a current-carrying conductor. To use this rule, point your thumb in the direction of the current flow, your index finger in the direction of the magnetic field, and your middle finger will then point in the direction of the force acting on the conductor. This rule helps in understanding the relationship between current flow and magnetic fields.
What statement describes the result of reversing the current in a current carrying wire in a magnetic field?
Reversing the current in a current-carrying wire in a magnetic field will reverse the direction of the force experienced by the wire. This is in accordance with Fleming's left-hand rule, where the thumb represents the current, index finger is the magnetic field, and middle finger indicates the force direction.
Suppose that you're facing a straight current-carrying conductor and the current is flowing toward you the lines of magnetic force at any point in the magnetic field will act in?
The lines of magnetic force at any point in the magnetic field of a current flowing towards you will act in the counter clockwise direction. This can be determined by using the right hand rule. Point your thumb in the direction of the current flowing down the straight wire. The curl of your fingers shows the direction of the magnetic lines of flux. The magnetic field of a current is always perpendicular to it. A current facing away from you would produce magnetic lines of force acting in the clockwise direction.

What is the purpose of Fleming's right hand rule?
Fleming's right hand rule is used to determine the direction of the magnetic force on a current-carrying conductor in a magnetic field. By aligning the thumb with the direction of current flow, the forefinger with the direction of the magnetic field, the middle finger points in the direction of the magnetic force acting on the conductor.
How can you determine the wind direction by wetting your finger and holding it up in the air?
You can determine wind direction by wetting your finger and holding it up in the air and feeling which side of your finger is being hit by the air. This would mean that the wind is coming from that direction.
What is the Difference between left hand rule and right hand rule?
Fleming's right hand rule shows the direction of induced current flow when a conductor moves in a magnetic field. Fleming's left hand rule shows the direction of the thrust on a conductor carrying a current in a magnetic field.
Which fingers are used in maxwell's left hand rule?
The thumb, the index finger and the middle finger.
What is the idea behind him about Fleming's left hand rule and right hand hand rule?
Fleming's right hand rule (for generators) tells us that if we take our right hand and extend the thumb, and also the index and the middle finger such that they are all at right angles to each other, we can discover the direction of the current induced in the wire of the generator. We'll have to know the direction of the motion of the conductor, and the direction of the magnetic field to do this. *Special note: the direction of the induced current will be the direction of conventional current in this mnemonic. Conventional current is the flow of positive charges in a conductor. We currently know that it is the negative charges - the electrons - that flow when current flows in a wire. But back in the day, theorists modeled the flow of positive charges, or what we call conventional current, and Fleming was an "old school" guy who worked with this conventional current. Let's apply Fleming's right hand rule to discover which way conventional current will flow in a wire in a generator. As stated, we have to know the direction of the motion of the conductor and the direction of the magnetic field. We have our right hand out and the thumb and first two fingers at right angles, each to the other. The thumb will point in the direction of the motion of the conductor. The index finger will point in the direction of the magnetic lines of force. We have motion of the conductor and the direction of the magnetic field. The middle finger will now point in the direction of conventional current flow in this mnemonic. Electron flow will be the opposite of that conventional current, if you are interested. But you knew that. Wikipedia has an article on Fleming's right hand rule, and a link to that post is provided below. The drawings alone are worth the trip over there, and the page is posted free of charge. Why not take advantage of this offer and check it out? It'll be worth it, and you won't get Rick rolled. Promise.
Flemmings left Hand Rule?
Fleming's left hand rule for motors is a visual depiction used to determine direction of rotation in a motor. Extend your thumb, index finger and middle finger of your left hand at right angles to each other. The thumb represents direction of relative motion. The index finger represents direction of flux (magnetic field). The middle finger represents direction of current flow. A simple way of remembering what each digit represent is the phrase: "Martha's Fresh Cookies." M being motion, F being flux and C being current. Fleming's Right hand rule for generators is the same except you use your right hand and it applies to direction of rotation of generators.
How is the left-hand rule related to current and magnetic field?
It is related to the flow of electrons in a conductor through aseparate magnetic field. If you point your index finger straight place your thumb up and place your middle finger at a 90 degree angle to the other two (unless you are really double jointed there is only one way to do it.). The direction of current and your wire is the middle finger the direction of magnetic plane pointing north is your index finger and the direction of force is your thumb. There is also the right hand rule. If you look at your right hand with your thumb up and fingers curved, If you held a piece of wire in your hand with the current traveling along the direction of your thumb the magnetic field would rotate in the direction of your fingers.
How can you determine wind direction by wetting your finger and hold it up into the air?
When you wet your finger and hold it in the air you can determine wind direction, if there is in fact wind, because the wind blows against your finger and chills the fluids on your finger. Therefore, whatever part of you finger is cold, in the direction the wind is coming from.
What statement describes the result of reversing the current in a current carrying wire in a magnetic field?
Reversing the current in a current-carrying wire in a magnetic field will reverse the direction of the force experienced by the wire. This is in accordance with Fleming's left-hand rule, where the thumb represents the current, index finger is the magnetic field, and middle finger indicates the force direction.
