प्रश्न
With the help of a labelled circuit diagram illustrate the pattern of field lines of the magnetic field around a current carrying straight long conducting wire. How is the right hand thumb rule useful to find direction of magnetic field associated with a current carrying conductor?
उत्तर
A labeled circuit diagram due to a current-carrying straight long conducting wire is shown below.
When current is passed through the conductor then concentric magnetic field lines will be produced. The strength of the magnetic field keeps on decreasing as we away from the wire.
We use the right hand thumb rule to find the direction of the magnetic field.
Right-Hand Thumb Rule : If a current-carrying conductor is held by the right hand; keeping the thumb straight and if the direction of the electric current is in the direction of thumb, then the direction of wrapping of other fingers will show the direction of the magnetic field.
