1. Drag and place the B-field directing to the coil, magnetic force(s) will exert on the side(s) which are influenced by the field.
2. The size of the B-field region can be varied by dragging its sides or corners.
3. The scale reading is the net vertical force (downward minus upward).
When the switch "Total - Zero" is turned to "Zero", the scale reading will become zero. Any reading shown afterwards is the force added after the switching. "N" and "mN" are units of force, standing for newton and millinewton, respectively.
Money is really very attractive!
