\n\n\n\nKey concepts:<\/h3>\n\n\n\n
\n
A current loop placed in a magnetic field experiences a force and torque due to the interaction between the magnetic field and the magnetic dipole moment created by the current in the loop.<\/li>\n\n\n\n
The current loop behaves like a magnetic dipole, with a magnetic moment $\\vec{\\mu}$ proportional to the current and the area vector of the loop (direction given by the right-hand rule).<\/li>\n\n\n\n
The torque $\\vec{\\tau}$ on a current loop in a uniform magnetic field $\\vec{B}$ is: $$
\\vec{\\tau} = \\vec{\\mu} \\times \\vec{B}
$$ This torque tends to rotate the loop so that $\\vec{\\mu}$ aligns with $\\vec{B}$.<\/li>\n<\/ol>\n\n\n\n
\n\n\n\nWhy the loop will rotate<\/strong> and not move upward<\/strong> or downward<\/strong>:<\/h3>\n\n\n\n
\n
While individual segments of the loop experience magnetic forces, the net force<\/strong> on a symmetrical loop in a uniform magnetic field is zero (forces on opposite sides cancel out).
However, these forces create a net torque<\/strong>, causing the loop to rotate rather than translate (move upward or downward).<\/li>\n<\/ul>\n\n\n\n
\n\n\n\nWhy it rotates counterclockwise<\/strong>:<\/h3>\n\n\n\n
\n
In this scenario, given the orientation, the torque causes a counterclockwise<\/strong> rotation.<\/p>\n\n\n\n
