Systems for repositioning objects, such as, for example, food items in a refrigerator, are provided. The systems may include a platform having a support surface upon which the objects are supported, an electromagnet positioned beneath the platform, a motion system coupled to electromagnet, and a control system electronically and/or communicatively coupled to the motion system and the electromagnet. The control system may be configured to controllably move the electromagnet beneath the support surface and to selectively activate and deactivate the electromagnet in coordination with said movement to reposition the objects. Related methods of repositioning objects are also provided.
