What was the secret to Lee's successful magic trick of moving a metal car without touching it?

The secret to Lee's successful magic trick of moving a metal car without physically touching it lies in the use of the paper wand having a magnet inside that attracted the metal. In this scenario, the wand is a tool that creates an unseen force, allowing the car to move as if by magic. By positioning the wand in proximity to the car, the magnet generates a magnetic field strong enough to pull the metal car toward it. This technique is a classic approach in magic acts, where the magician utilizes a hidden mechanism or object to create an illusion of impossible feats.

The other options suggest methods that don't align with the physical properties involved in moving the metal car. Mirrors create visual illusions but wouldn't enable direct movement of the car itself. Using air to move the car would be impractical and ineffective due to the car's weight and lack of aerodynamic features. Lastly, if the car were on a slight incline, it could potentially move on its own, but that wouldn't constitute a magical trick requiring skill or trickery, as the effect would rely solely on gravity rather than any manipulation by the magician.
