A small bar magnet is placed in a magnetic field B(\(\vec{r}\)) = B (x)\(\hat{z}\). The magnet is initially at rest with its magnetic moment along \(\hat{y}\). At later times, it will undergo
1
angular motion in the yz plane and translational motion along \(\hat{y}\)
2
angular motion in the yz plane and translational motion along \(\hat{x}\)
3
angular motion in the zx plane and translational motion along \(\hat{z}\)
4
angular motion in the xy plane and translational motion along \(\hat{z}\)
