Which of the following is the correct expression for force due to a magnetic field $(\vec{B})$ on a straight conductor of length $(l)$ carrying current I? |
$\vec{F}=I(\vec{B} \times \vec{l})$ $\vec{F}=\vec{B}(\vec{I} \times \vec{l})$ $\vec{F}=I(\vec{l} \times \vec{B})$ $\vec{F}=l(\vec{I} \times \vec{B})$ |
$\vec{F}=I(\vec{l} \times \vec{B})$ |
The correct answer is Option (3) → $\vec{F}=I(\vec{l} \times \vec{B})$ |
