Acurrent loop lies in the xy plane of an xyz coordinate system, with the current circulating counterclockwise when viewed looking down the positive z axis toward the origin. the loop experiences a torque about the x axis that is counterclockwise when viewed looking down the positive x axis toward the origin. part a describe the direction of the uniform external magnetic field responsible for this torque. describe the direction of the uniform external magnetic field responsible for this torque. the magnetic field is in the positive y direction. the magnetic field is in the negative x direction. the magnetic field is in the positive x direction. the magnetic field is in the negative y direction. the magnetic field is in the positive z direction. the magnetic field is in the negative z direction. request answer
