Ampere's right hand thumb rule states that if you hold the current carrying wire in your right hand so that your thumb points in the direction of the current, then the direction in which your fingers encircle the wire give you the direction of the magnetic lines of force around the wire .On reversing the direction of current in the
wire , the direction of the magnetic lines of force is also reversed.
*Note: When we talk about the left hand and right hand rules, we have some confusion built into the ideas. The confusion comes from the "old school" model that said electric current flowed from positive to negative. This is the so-called conventional current picture of electricity. Conventional current flows from positive to negative. It is electron current that flows from negative to positive. And that's what actually happens, and how we see things today. But both ideas as regards current flow are still kicked around. If we use Fleming's rule to work things out, then the current direction indications will have to be "reversed" to understand the mnemonic. Be sure to have an accurate picture of which rule and which method of current flow is being used to explain a given electrical situation!
For a wire, the left hand rule states that if the wire is grasped by wrapping the hand around it with the thumb pointing in the direction of electron flow, the fingers will be In a generator, if we apply the left hand rule (using electron flow instead of conventional current), we can find the direction of (electron) current flow that is induced in the conductor if we know the direction of the movement of the conductor and the direction of the magnetic field. Extend the left hand, and stick out the thumb. Then stick out the index finger in a direction that is an extension of the arm. The tumb will be "up" and the index finger will be "out" at 90 degrees from the thumb. Now stick out the middle finger to form a 90 degree angle with both the thumb and the index finger. Now you have a digit pointing in each of three directions that are mutually 90 degrees apart, each one from the others. Let's apply this mnemonic.
By pointing the thumb in the direction of the movement of the wire, and the index finger in the direction of the magnetic field, the middle finger will be pointing in the direction electrons will be moving as a result of the induced voltage in the conductor. It's just that simple and easy. Remember that both these mnemonics are "opposite" of Fleming's left hand rule, because we chose to speak to electron flow rather than use the idea of conventional current.
Left hand is for motor and right hand for generator.
Fore finger in both the direction of Field. Note "F"
Centre finger is for the current, of course, conventional current. Note down "C"
The Main finger is for the Movement of the conductor. Note "M"
Main is thumb. Middle finger, of course, is taken to be the centre.
quantitative measure of the extent to which a material may bemagnetized in relation to a given applied magnetic field. Themagnetic susceptibility of a material, commonly symbolized by chim,is equal to the ratio of the magnetization M within the material to theapplied magnetic field strength H, or chim = M/H. This ratio, strictlyspeaking, is the volume susceptibility, because magnetizationessentially involves a certain measure of magnetism ( dipole moment)per unit volume
Just wash your hands an lotion them an you will be fine
If you clasp your hand with your left thumb over your right, this is a dominant (more common) way of doing so. People who clasp their hands with their right thumb on top have the recessive genes. Left hand on top- Ll or LL right hand on top- ll

There is no left handed rule. The correct term is right handed rule. Using the right handed rule, your thumb is pointing in the direction of current flow, and your fingers are pointing in the direction of magnetic flux flow.
Finger next to the thumb, i.e. To the immediate right of the thumb on your right hand To the immediate left of the thumb on your left hand
Ampere's right hand thumb rule states that if you hold the current carrying wire in your right hand so that your thumb points in the direction of the current, then the direction in which your fingers encircle the wire give you the direction of the magnetic lines of force around the wire .On reversing the direction of current in thewire , the direction of the magnetic lines of force is also reversed.
Use the right hand rule. Take out your right hand, wrap your hand around the loop, your fingertips should curve to the direction of the wiring, that is, the current should be coming out from your wrist to your fingertip, and the direction of your thumb is the magnetic fieled produced. The thumb is N, and the other is S.Alternative AnswerThe left-hand 'grip' rule for determining the magnetic polarity of an electromagnet applies for ELECTRON FLOW current direction -i.e. current flow from negative to positive. Grasp the electromagnet with the curl of the fingers pointing in the same direction as the electron flow current, and the thumb will indicate the north pole end of the electromagnet.For CONVENTIONAL FLOW (positive to negative), we use the right-hand 'grip' rule instead.
Curl the fingers of your right hand into the palm and extend the thumb. The thumb indicates the direction of the current, and the direction of the fingers indicates the direction of the magnetic field.
The "Right Hand Rule" Put your right hand under the wire with your thumb sticking out and in the direction of the flow of the current (note that it is opposite to the direction of the movement of the electrons!) and close your fist; the fingers of the right hand will curl around in the direction of the magnetic field.
I'm not familiar with the corkscrew analogy, but the right hand rule is a method for coordinate systems and cross products.Take your right hand and put out the thumb, index finger, and middle finger at right-angles to each other.Your index finger is the direction of the positive x axis.Your middle finger is the direction of the positive y axis.Your thumb is the direction of the positive z axis.So if you orient your hand like a regular x-y graph, with index (x) toward the right, and middle (y) pointing up, then your thumb (z) will be pointing straight at you.
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
When electric charge flows from one place to another, it induces a magnetic field. The direction of the magnetic field is found by the right hand rule. To use the right hand rule, put your right hand into a fist with your thumb pointed up. When your point your thumb in the direction of the current, and the direction your fingers gives you the direction of the magnetic field.
