magnetic force

Magnetic force on current-carrying wires

  • Drag and place the B-field directing to the coil, magnetic force(s) will exert on the wire(s) lying inside the field.
  • The size of the B-field region can be varied by dragging its sides or corners.
  • When the switch "Total - Zero" is turned to "Zero", the scale reading will become zero. Any reading shown afterwards is the "weight" added after the switching.
  • "N" and "mN" are units of force, standing for newton and millinewton, respectively.
