Web14 de fev. de 2024 · Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the … Web17 de dez. de 2024 · Hold the steel bar flat on a table so one end is pointing toward you. Touch one end (north or south) of the bar magnet to end of the steel bar closest to you. Move the magnet along the steel bar’s length until you reach the end away from you. The steel bar should remain still. You’re moving the magnet, not the steel bar.

Web13 de dez. de 2024 · Moving magnetic fields pull and push electrons. Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. WebFind a metal object (ie nail, screw, paperclip) Find a power source Foil the copper around the metal (insulated) The first step should seem quite simple: finding a metal object that can be magnetized. This can be something as small as that of a paperclip or nail that are often laying around at desks of old hardware stores.
To make a magnet, start by removing 1-2 inches of insulation from both ends of a copper wire. Next, wrap the wire tightly around a nail, starting about 8 inches from the end of the wire and working your way down until the nail is covered from head to tip.
