Explain the ‘right hand thumb rule’ to know the direction of magnetic field.

The direction of the induced magnetic field from a current carrying conductor is given by the Right hand thumb rule. According to Right hand thumb rule:-

•When we place our right hand's thumb in the direction of the current and as we wrap our finger around the current carrying conductor.

•Wrapped finger will show the direction of the magnetic field.

•It is noticeable that the wrapped finger from a close loop which is the most important property of the magnetic field.

Hence, when we place our right hand's thumb in the direction of the current carrying wire the circular rings formed by our finger will denote the magnetic field.
