Confused on these two questions. Please explain on how to get these answers

If an external magnetic field is applied in the positive z direction the loop will turn. True False You've created your electric motor, however, you still aren't getting enough torque. You have maxed out your current source, and have only one external magnet. What is the most efficient way to increase the torque? (you have two options, which one would increase the torque the most?) change the direction of the current panic and run away add more loops reverse the direction of the external magnetic field

Explanation / Answer

Ans (1) False   

Because the direction of on loop is radially outward direction throughout the circumference so the maintain its position.

Ans (2) as we know
   torque = N.I.A.B

So we add more loops and increse number of turns so torque increses.
