Science Museum Exhibit/ Exhibition/ Education Equipment iron bridge

Product Overview

Description

Using the principle of the magnet opposites attract, the exhibition item understands the knowledge about electromagnet and magnetic force through the bridge operation.One side of the booth is equipped with extremely strong magnets, and the other side is equipped with extremely strong negative magnets, which are magnetized by a nail, and then attract other nails to magnetize to form a "nail bridge" like suspension cable.When participating in the exhibition, the audience will press the power button and then pick up the nails inside the booth. Starting from one end, the nails will be magnetized one by one. Finally, the nails will be attracted to the magnets on the other side and form a nail bridge.




Electromagnet is a kind of device that generates electromagnetism when electrified.An electrically conductive winding that is wound around the outside of the core to match its power. The current flowing coil is magnetic like a magnet. It is also called an electromagnet.We usually make it into strips or hoofs to make the core more magnetized.
