Abstract: An electromagnet is attached to the outer surface of at least one of the tines of a grapple. Preferably, the electromagnet is attached near the free end of the tine so that the bottom surface of the electromagnet, which extends between the inner and outer poles of the electromagnet, faces downward when the grapple is in the closed position. Preferably, the electromagnet is attached to the tine so that the bottom surface of the electromagnet is at or very close to the lowest point of the grapple when the grapple is in the closed position. It is also possible to attach respective electromagnets to any one of the plurality of tines, such that more than one of the plurality of tines has an electromagnet attached thereto.
