Top Levitation
Bottom Levitation
Characteristic 
Magnetic force rise up with levitation lifting height decreasing from Top base. The objects weight is counteracted by gravitational force. Magnetic force is permanent for a designed Device. Top Levitation apply to levitating bottles, Levitating can,  Top of products are requested as complanate as possible. It only can leviate a fixed weight, But can not levitate ranges of weight.
Top Levitation
An object is suspended by Magnetic force produced from underneath base. The objects weight is counteracted by magnetic repulsive force. Magnetic force rise up with levitation lifting height decreasing.Bottom levitation modules can levitate a widely range of weight, it solved levitating capacity restrained problem, widely used.
Bottom Levitation
Capacity 
Levitate a fixed weight 
Can not support ranges of weightate a range of weight.
Top Levitation
Levitate ranges of weight
Levitating object max 3kg
Bottom Levitation
Levitating height
 Approximately  20mm
Height is fixed
Top Levitation
Max up to 60mm
Height reduce with Weight of object rasing up
