Question

When a current carrying conductor is held in a way that the thumb faces the direction of the current, the direction of the curl of fingers corresponds:

• A. To the direction of the magnetic field
• B. To the direction opposite to that of magnetic field
• C. Perpendicular to the direction of magnetic field
• D. To nothing

Answer 1

The correct option is A

To the direction of the magnetic field

The right hand thumb rule states that if we hold a current carrying conductor in such a way that the thumb points in the direction of the current, the direction of curl of the fingers will give the direction of magnetic field.
