## Homework Statement

As shown in figure above, a conductor RS with 2 m length which is powered with currents is put in a 0.5 T magnetic field. If the force generated by the conductor is 1 N into-the-screen, then the magnitude and direction of the current in conductor is ...

A. 1 A from R to S

B. 1 A from S to R

C. 2 A from R to S

D. 2 A from S to R

E. 5 A from R to S

## Homework Equations

F = BIL sin θ

## The Attempt at a Solution

1 = 0.5 I 2 sin 90°

I = 1 Ampere

And, the direction is from S to R

(I point my 4 fingers to the right side, my palm inward, so the thumb (current) points upward)

Is it correct?? I need to make sure about this... I'm self-studying

Thanks in advance
