A conductor is placed along z-axis carrying current in z direction in uniform magnetic field directed along y-axis. The magnetic force acting on the conductor is directed along:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → negative x-axis
Given:
Current (I) → along z-axis → $\hat{z}$
Magnetic field (B) → along y-axis → $\hat{y}$
Magnetic force on conductor: $\vec{F} = I (\vec{L} \times \vec{B})$
$\hat{z} \times \hat{y} = -\hat{x}$
∴ Magnetic force is directed along negative x-axis.
Answer: Along –x direction
