The idea is that the weight of the one ring (mRingg) would be simulated by the weight of the Ironring + the force of the magnetic field (mIronring + FB), according to the principle sketch. I measured it with a Hall effect sensor. I appreciate your help, but I've handed in the assignment now.

I found this formula (source, page 284) fm = m * χ0 * µ0 * H * grad(H) m and µ0 are already known. χ0 is determined by and (source) H is determined by B/µ Is there somehow possible to calculate grad(H) or at least simplify it by making some assumptions? I'm really in need for some results.

With the field gradient, do you mean the inclination of the field? For I can assure you that the ring was stationed at the axis of the magnetic field. Would I get a result if I assumed that the ring was magnetized before? In that case, how would that calculation look like? I'm really desperate...

I decided to simulate this scene in Lord of the Rings for a project in school with the purpose of calculating the "real" mass of the One Ring. I've done the experiments according to this principle sketch but I have some troubles with calculating the magnetic force that the copper coil is...

I'm studying science in the last years of my gymnasium. Really looking forward to discuss physics and contribute to this community.
