Question

The magnetic force $\overline{F}$ on a current carrying conductor of length l in an external magnetic field $\overline{B}$ is given by:

• A. $\frac{I\times \overline{B}}{\overrightarrow{l}}$
• B. $\frac{\overrightarrow{l}\times \overline{B}}{I}$
• C. $I(\overrightarrow{l}\times \overline{B})$
• D. $I^2\overrightarrow{l}\times \overline{B}$

Answer 1

The correct option is C $I(\overrightarrow{l}\times \overline{B})$

It is known that: $\overrightarrow{F_B}=I(\overrightarrow{l}\times \overrightarrow{B})$
