    I would put the child on the carrousel with the magnetometer and put te bar magnet and the charged ball in the middle. This way the child sees the contribution of the bar magnet and a rotating charge (in the childs perspective). This is two out of the 3 contributions, to get the fermi contribution, you would need to get a second charge very close to the child. If there is only one charged ball, the approximation would be better if the charged ball is near the child and not in the center, because this contribution is larger
