Question:

Biot-Savart law indicates that the moving electrons (velocity $\vec{v}$) produce a magnetic field $\vec{B}$ such that:

Options:

$\vec{B} \perp \vec{v}$

$\vec{B} || \vec{v}$

It obeys inverse cube law

It is along line joining the electron and point of observation

Correct Answer:

$\vec{B} \perp \vec{v}$

Explanation:

The correct answer is Option (1) → $\vec{B} \perp \vec{v}$
