Magnetic Levitation Kit – DIY Floating Ball with Electromagnet & Light, STEM Model

Make a ball float in the air

This kit builds a magnetic levitation display. A coil in the top housing works as an electromagnet, and a control circuit keeps adjusting its pull so it exactly balances the weight of the orange ball. Set the ball in the right spot about 1–3 cm below the housing, let go, and it hangs in mid-air while the base lights up; slide a sheet of paper between them to prove nothing is touching.

Science it demonstrates

• Electromagnets: a coil carrying current becomes a magnet
• Magnetic force against gravity
• Feedback control: how the circuit keeps the ball stable
• Real-world maglev: trains and frictionless bearings

What you'll do

• Assemble the base, battery box and curved support
• Fit the coil and control board into the top housing
• Install the batteries and switch on
• Find the balance point and let the ball float

Parts list

• Base with battery box, switch, light and decorative ring
• Curved support and coil housing with control board
• Orange ball with magnet
• Screws and a screwdriver

Good to know

• Needs 4 × AA batteries (not included).
• Finding the floating point takes a little patience: move the ball slowly.
• Contains small parts. Recommended for ages 8 and up, with adult guidance.
