Imagine a magnetic field in front of you , where direction is towards left to right hand . If a wire is hanging vertically in front of you , in which current is flowing in the upward direction , then in which direction the wire will be deflected ?
Answers
Answer:
The right-hand rule is based on the underlying physics that relates magnetic fields and the forces that they exert on moving charges—it just represents an easy way for physicists to remember the directions that things are supposed to point. Occasionally a physicist will accidentally use their left hand, causing them to predict that the magnetic force will point in a direction opposite the true direction!
Explanation:
Magnetic Field due to a Current-Carrying Conductor:
The direction of the magnetic field produced at a point due to a current-carrying conductor is given by any one of the following rules:
Amperes swimming rule: Imagine a man swimming along the current-carrying conductor in the direction of the current. The north pole of the magnetic needle kept underneath the wire will be deflected towards the left hand of the man.
Fleming's Right hand rule: Hold a current-carrying conductor in your right hand with thumb in the direction of the current, the direction of the field lines will be the direction of your fingers.
Maxwells Cork Screw rule: Imagine a right handed cork screw with its axis coincident with the current carrying wire. Now rotate the screw to advance it in the direction of the current, the direction in which the thumb rotates gives the direction of the magnetic field lines.
