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.

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.


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.


How do you moisten dry soil?

Use a soil wetting agent which will stop the soil repelling water. Slow watering, such as with drip irrigation allows the soil to absorb water better than a large amount delivered in a short space of time.


How do you know that a force is negative or positive in relation to magnetic field?

It depends on what direction is considered positive and what direction is considered negative. For this case, I'll assume that up, right, and outward are positive and down, left, and inward are negative. Since the force is perpendicular to the magnetic field, the sign for the force depends on the direction of the current. If the current is inward and the magnetic field is to the left, then the force is upward and thus positive. If the current would be outward and the magnetic field would be still to the left, then the force is downward and thus is negative. The best way to think of this is to use the "right-hand" rule. Use your index finger to represent the direction of the current, your thumb as the direction of the force, and the other three fingers as the direction of the magnetic field direction.


What weather instrument could tell you that conditions are right for flying a kite?

A weathervane will show you which way the wind is blowing.Some people wet their finger and hold it up to feel what way the wind is blowing but I don't think that is as realiable HA HA.

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 is the three finger rule in physics and how is it used to determine the direction of a magnetic field?

The three finger rule in physics is a method used to determine the direction of a magnetic field around a current-carrying wire. To use this rule, point your thumb in the direction of the current flow, and your fingers will curl in the direction of the magnetic field.


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?

When you dipped your finger into the water what direction did it transfer?

When I dipped my finger into the water, the water transferred in the opposite direction to my finger's movement.


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 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.

Ways to measure wind direction without a wind vane?

You can use a windsock, wet finger, or the behavior of smoke to determine wind direction without a wind vane. Additionally, observing the movement of tree leaves or flags can also help you gauge wind direction.


What is the significance of a child holding on to a finger?

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 do roman gladiators surrendor?

A gladiator would surrender by stopping fighting and holding up one finger. If he wanted to be dramatic, he could get down on one knee and hold up the finger. At any rate, the raised finger was the signal that he was surrendering.A gladiator would surrender by stopping fighting and holding up one finger.
