🕹️Increasing the weight of a spinning top leads to increased friction.
🧲The repelling force between matching poles of magnets can be used to levitate a flywheel.
⚙️A frame made of aluminum extrusions can support magnets for levitation.
🔩Opposing poles of magnets on an axle allow for magnetic levitation.
🔄Spinning magnets induce current in coils to generate electricity through magnetic induction.
How does increasing the weight of a spinning top affect its spin time?
—Increasing the weight increases friction, reducing the spin time.
What force is used to levitate the flywheel?
—The repelling force between matching poles of magnets is used to levitate the flywheel.
What material is used to build the frame?
—The frame is built using aluminum extrusions.
How are magnets arranged on the axle for levitation?
—Opposing poles of magnets are arranged on the axle.
How is electricity generated from spinning magnets?
—Spinning magnets induce current in coils through magnetic induction, generating electricity.
