| + !Taking the torque into account |
| + |
| + In general, the forces or not only radial but also tangential, |
| + inducing a torque onto the magnet. For estimating the forces |
| + on the fixation, we need to take into account the distance of |
| + the fixation points from the coil center. |
| + |
| + For MA7, with a mean coil radius of about 100 m and fixation points |
| + at about 150 mm for the coil center, we get the following: |
| + |
| + Ro: object distance (mm)\\ |
| + phi: angle (deg) between field direction and direction of object, for maximum force on fixation\\ |
| + Fp: force when object on magnet axis (in field direction) |
| + Ft: maximum total force on fixation |
| + |
