Question

A square loop having length of side $$1$$ m is liying in the xy plane. A uniform magnetic field B→$$=2i^$$−$$3j^+k^T$$ exists in that region of space. If the loop carries a current of $$2A$$, the magnitude of torque experienced by the loop is,

magnetic dipole moment of the loop M→$$=2$$×$$12k^$$   N−$$m=2$$ $$k^$$  N−m∴τ→$$=M$$→×B→$$=2k^$$×$$2i^$$−$$3j^+k^$$ N−$$m=4j^+6i^N$$−m∴τ→$$=42+62$$  N−$$m=52$$  N−m

A square loop having length of side 1 m is liying in the xy plane. A uniform magnetic field $\vec{B} = (2 \hat{i} - 3 \hat{j} + \hat{k}) T$ exists in that region of space. If the loop carries a current of 2A, the magnitude of torque experienced by the loop is,
