Question

In the given diagram, what would be the direction of the magnetic field at point A?

• A. Into the page
• B. Out of the page
• C. Along the direction of flow of electrons
• D. Opposite to the direction of flow of electrons

Answer 1

The correct option is A Into the page

The direction of the magnetic field around a current carrying conductor can be determined using the right-hand thumb rule.
In the given scenario, the electrons are flowing rightwards. Therefore, the direction of current is leftwards.
As per the right hand thumb rule, the direction of the magnetic field at point A will be into the page.
