What is the rule relating to the direction of the field due to the current in a wire?
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.

What technique is used to determine the direction of the magnetic field around a current carrying conductor?
The right hand rule is a simple way to find out the direction of the field surrounding a current carrying conductor.Point your right thumb in the direction of the current in the wire (which flows from high to lower voltages) and curl the other fingers as if around the wire; the curled fingers define the direction of the magnetic field generated.CommentIt might be worth pointing out that the above answer applies for conventional flow, not electron flow.
What is formed around a wire when electricity flows through it?
Current through a conductor forms a magnetic field.The "Right Hand Rule" will tell you the direction: Point the thumb of your right hand along the conductor in the direction of current flow (from negative to positive) and the fingers of the right hand curl in the direction of the magnetic field force lines.
What shape is magnetic field produced when current is passed through the wire?
it is called the thumb rule right hand curled means flux line thumb means direction of current. there will be a reversal of flux.
When you're using the right-hand or generator rule your middle finger indicates the direction of what?
conventional current flow
How does the left hand rule apply alternating current generator?
your thumb will point to the diretion of the rotation...and you forefinger will point to the direction of the magnetic fluxAnswerFleming's Left-Hand Rule applies to motors when using 'conventional flow' and to generators when using 'electron flow'. So, assuming you are talking about electron flow, the thuMb indicates the direction of Motion of the conductor relative to the flux, the First finger indicates the direction of the magnetic Field (north to south), and the sEcond finger indicates the direction of the E.m.f. induced into the conductor. This applies whether the generator as an a.c. machine or a d.c. machine.
What happens to the direction of a magnetic field around an electric current when the direction of the current is reversed?
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
What is the right hand rule for current in a wire and how is it applied to determine the direction of the magnetic field produced by the current flow?
The right-hand rule for current in a wire states that if you point your right thumb in the direction of the current flow, then the direction your fingers curl around the wire represents the direction of the magnetic field produced by the current. This rule helps determine the relationship between the direction of current flow and the resulting magnetic field around the wire.
How can one determine the direction of current in a magnetic field?
To determine the direction of current in a magnetic field, you can use the right-hand rule. Point your right thumb in the direction of the current and curl your fingers in the direction of the magnetic field. Your fingers will then point in the direction of the force acting on the current.
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.
What is the right hand rule and how is it used to determine the direction of a magnetic field around a current-carrying conductor?
The right-hand rule is a method used to determine the direction of a magnetic field around a current-carrying conductor. To use the rule, point your thumb in the direction of the current flow and curl your fingers. The direction your fingers curl represents the direction of the magnetic field around the conductor.
What is the right hand rule for determining the direction of a magnetic field when a current is flowing out of the page?
The right-hand rule states that if you point your right thumb in the direction of the current flow, your fingers will curl in the direction of the magnetic field.
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.
How can one determine the direction of the magnetic field generated by a current?
To determine the direction of the magnetic field generated by a current, you can use the right-hand rule. Point your right thumb in the direction of the current flow, and your fingers will curl in the direction of the magnetic field.
Why and when does a current carrying conductor kept in a magnetic field experiences a force list factor on which the direction of this force depend State the rule which may be used to determine the di?
Current carrying conductor will have magnetic lines around it. So when it is kept perpendicular to the magnetic field then the force would be maximum. The force depends on 1. magnitude of current 2. Magnetic field induction 3. Angle between the direction of current and magnetic field. Fleming's Left hand rule is used to find the direction of force acting on the rod
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.
The direction of a magnetic field produced by an electric current depends on the direction of the what?
The direction of a magnetic field produced by an electric current depends on the direction of the current flow. The magnetic field will form circular loops around the current-carrying wire, following the right-hand rule.
Effect on the magnetic field when the direction of current is reversed true or false?
True. When the direction of the current is reversed, the direction of the magnetic field also reverses. This is in accordance with the right-hand rule for determining the direction of the magnetic field around a current-carrying conductor.
