1. A work machine comprising:
a lower traveling structure;
an upper swing structure mounted on the lower traveling structure via a swing mechanism;
an attachment attached to the upper swing structure;
a lifting magnet attached to the attachment; and
a hardware processor configured to
calculate a weight of an object lifted by the lifting magnet;
simultaneously display the calculated weight of the object and an image captured by an image capturing device on a display; and
calculate a remaining weight as a target weight by subtracting a cumulative value of the weight of the object from a maximum loading capacity of a dump truck and control an attraction force of the lifting magnet based on the target weight.
