the science behind what is happening during magic moving wire experiment
The magic moving wire experiment involves creating a magnetic field by passing an electric current through a wire. The wire is then placed near a magnet and experiences a force that causes it to move. This phenomenon is explained by the laws of electromagnetism and Newton's third law of motion.
When an electric current flows through a wire, it creates a magnetic field around it. The strength of this magnetic field is directly proportional to the amount of current flowing through the wire. In the magic moving wire experiment, the wire is positioned in close proximity to a magnet so that the magnetic field from the wire interacts with the magnet's field.
When the two fields interact, the wire experiences a force due to the magnet's field. This force is called the Lorentz force and is proportional to the strength of the magnetic field, the current flowing through the wire, and the length of the wire. As a result, the wire moves in a direction perpendicular to the magnetic field and the current flow.
Additionally, Newton's third law of motion comes into play. This law states that for every force, there is an equal and opposite reaction force. So, when the wire experiences a force due to the magnetic field, it exerts an equal and opposite force on the magnetic field. This is why the magnet may also move slightly during the experiment.
In summary, the magic moving wire experiment demonstrates the interaction between electrical currents and magnetic fields, and the resulting forces experienced by the wire and nearby magnets.
