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.

What happens when a compass is palced near a current carrying conductor?
If the conductor is carrying AC, no effect. If the conductor is carrying DC, then the compass needle will be deflected. Provided the two are close enough, and the DC current is strong enough.
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.
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?
A clockwise direction
How can one determine the direction of the magnetic field for a current carrying wire?
Curl your right-hand fist around the wire, with your thumb pointing in the direction of the current in the wire. Your four curled fingers point in the direction of the magnetic field that surrounds the wire.
What will happen if a compass is suspend next to a conductor that is not carrying an electron flow?
Nothing will happen.
When does current carrying conductor placed in a magnetic field experiences a maximum force?
It experiences maximum force when it is placed perpendicular to the direction of magnetic field.
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 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 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.
Why does current carrying conductor experience force when kept near a magnet?
The current carrying conductor has a magnetic field of of its own so when it comes in contact with with another magnetic field it experiences a force which is given by fleming's left hand rule.The force depends upon :direction and the strength of the magnetic fielddirection and the strenth of the current
What is the principle of motor action?
Motor runs by the principle of Michael Faraday's Electromagnetic Induction. It is defined as "when a current-carrying conductor is located in an external magnetic field perpendicular to the conductor, the conductor experiences a force perpendicular to itself and to the external magnetic field". The direction of rotation is determined by the Right-hand Rule and is "if the right thumb points in the direction of the current in the conductor and the fingers of the right hand point in the direction of the external magnetic field, then the force on the conductor is directed outward from the palm of the right hand".

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.
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 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 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 happen when a current carrying conductor is placed in a magnetic field?
A force will be applied to the conductor. This is the operating principle of the motor.When a current carrying conducter is placed in magnetic field it experiences a force.Reason :- Force(F') on a charged particle(q) moving with velocity v' due to magnetic field(B') around it isF' = q (v'xB') where F', v', B' are vectorsand v'xB' is vector product or cross product which also gives the direction of this Force vector F'.Current, as we know, is caused due to motion of electrons. So, when a current carrying conductor is placed in magnetic field, these moving electrons experience force and so does the Conductor too.If the force on electrons is summed up or integrated over the entire length(L) of a straight conductor. We will end up withF = BIL where I is the current. Direction of this force is determined by cross product of direction of current and Magnetic Field.
