There is no such thing as an 'induced current'. What is 'induced' is a voltage. If the conductor into which that voltage is induced forms a complete circuit, then a current will result. But it's the voltage that's induced, NOT the current!
The direction of the induced voltage is explained by Lenz's Law which, in simple terms, tells us that the direction of the inducted voltage is always such that it will oppose the change in current that causes it. So the induced voltage will oppose any increase in current, but will act in the same direction as a reduction in current.

How is it used in determining the direction of the magnetic field around a conductor carrying current?
By using right hand rulee.. how?? let me explain.. first you should be knowing the direction of flow of current, then hold the current carrying conductor by your right hand in a way that your thumb points the direction of current flowing and curl your fingures around the conductor the manner your figures curl around condutor would determine the the magnetic field's direction that may be clockwise or anti-clockwise..thankkxx.
How rigt hand thumb rule is used in determining the direction of magnetic field around a conductor carrying current?
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.
Why you get electric shock when current flows opposite direction in a conductor?
When current flows in a conductor you do not get an electric shock provided you do not touch the conductor.
Is silicon rectifier a good conductor or good insulator?
It's a good conductor of current flowing in one direction, and a good insulator when current tries to flow in the other direction.
Which law gives the direction of magnetic field due to a current carrying conductor?
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.
Explain why current is not a vector though it appears to posses a direction?
Its direction is wherever the conductor goes. Once the conductor is configured, the current has only two choices ... forward or backward, denoted by positive or negative current.
what rule is applied in case of dc motor?
You may be thinking of Fleming's Left-Hand Rule (for conventional current flow) or Fleming's Right-Hand Rule (for electron flow), devised by academic Sir Ambrose Fleming, as a aid for determining the direction of the resulting force acting on a current-carrying conductor within a magnetic field, when the direction of current and the direction of the magnetic field are known.
What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
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.
Why cannot the B-field of an infinitely long straight current-carrying conductor have a component in the direction of the current?
As induced magnetic lines exist in a plane perpendicular to the direction of flow of current, the component in the direction of current i.e cos 90 component will be zero. Recall cos 90 = 0. Hence the answer
What is the Flemings left hand rule?
The direction of force produced on a current-carrying conductor placed in a magnetic field can be determined by this rule. the thumb, forefinger and middle finger of the left hand mutually at right angles to each other, such that the forefinger is in direction of flux, and the middle finger is in a direction of current flow in the conductor, then the thumb indicates the direction of motion of the conductor.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
What is the relationship between magnetic fields and electricity?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
