Magnetic field lines around a current carrying wire are drawn in clockwise direction on a page. The current is flowing:
Correct answer: A. Into the page
- A. Into the page
- B. Out of the page
- C. Left side of the page
- D. Right side of the page
Explanation
The correct answer is 'Into the page'. According to the right-hand rule, if you point your thumb in the direction of the current (which is assumed to be flowing into the page), your curled fingers will point in the direction of the magnetic field lines. Since the question states that the magnetic field lines are drawn in a clockwise direction, this indicates that the current must be directed into the page.Options 'Out of the page', 'Left side of the page', and 'Right side of the page' are all incorrect because they do not align with the right-hand rule's prediction for a clockwise magnetic field. If the current were flowing out of the page, the magnetic field would be counterclockwise, not clockwise.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
