Display arrangement having magnet that interacts with a coil to induce movement of the display arrangement

A display arrangement comprising:

• a base;
• a decorative shell that is supported over the base;
• a support post having upper and lower ends;
• the lower end of the support post being fixedly coupled to the base;
• a stem having upper and lower ends;
• a magnet;
• the lower end of the stem supporting the magnet;
• the upper end of the stem being pivotally coupled to the support post at an intermediate location thereof between the upper and lower ends of the support post;
• and
• a coil configured to receive energy from a power source to cause an arcing motion of the magnet and the stem, and a corresponding rotational movement of the decorative shell.

A display arrangement comprising:

• a base;
• a lower shell;
• a middle shell that is rotatably coupled to the lower shell;
• a top shell that is rotatably coupled to the middle shell;
• all of the lower, middle and top shells being aligned in sequence over the base;
• a stem coupled to at least the middle shell, the stem having a magnet on one end;
• and
• a coil configured to receive energy from a power source to cause an arcing motion of the magnet and the stem, to thereby cause the middle shell, the lower shell, and the top shell to rotate.
