A hinge includes a pivot, two connection members pivotally connected by the pivot, a first magnetic part connected to one of the connection members, a second magnetic part moveably disposed relative to the first magnetic part and kinetically connected to the other one of the connection members, and an adjustment part kinetically connected to the other connection member and urging against the adjustment part. The magnetic moment of the second magnetic part is opposite to that of the first magnetic part. When the two connection members rotate relatively, the other connection member drives the adjustment part and the second magnetic part to rotate relative to the first magnetic part, so as to produce a repulsive moment resisting the rotation and varies with the rotation. A foldable electronic apparatus has the hinge.
