Scientific Enlightenment:

Trains are pulled by locomotives (commonly known as the train's head) with dynamic machinery, moving along the rails. Trains are an important part of modern transportation, in addition to transporting passengers, they are also the main means of long-distance freight transportation, with the advantages of large load capacity and low transportation cost. In addition, in large coal mines and factories, trains are also used to complete internal transportation tasks. Trains have a history of more than 100 years. The earliest trains were made by the British Stephenson in 1814. By 1825, the "Dynamo" No. 1 locomotive he made set the record for the highest speed on land at 24 kilometers per hour. Over the following decades, trains gradually became an important means of transportation, and European countries and the United States began to construct large-scale railways, marking the beginning of the railway era for humans. The emergence of trains and railways enabled people to travel longer distances more quickly, making it easier to obtain the necessary materials from far away and to transport products to distant places for sale, all of which greatly promoted the development of production and improved the living standards of people. Now that we know the origin of trains, let's get started making a small magnet train together.


Scientific Principles:

When a battery with a magnet adhered to it enters a copper coil, the current in the battery creates a magnetic field. The magnetic field of the copper coil repels the magnet, causing the battery to move. The current in the battery, which is positive and negative, moves along the copper wire, and the magnet on the battery pulls and repels each other, creating the invisible force that pushes the battery forward smoothly.

Science Project:

1. Recognize and prepare the necessary equipment for the experiment.
2. Perform the experiment according to the instructions in the manual.

Science Expansion:

A small train from rest to motion must have been subjected to the action of force. The forces that may be generated during the motion process of the small train include friction, Amperes force, and air resistance. Friction and air resistance can hinder motion, and it is very likely that Amperes force is what makes the battery move. Basic common sense is that 1. Magnets can adhere to the battery because there is a iron core inside the battery, and the properties of the battery will not change because of the attachment of the magnet. 2. Magnets have the property of conductivity, and the copper wire, magnet, and battery may form a circuit in the experiment. The next question is how Amperes force is generated and how it acts on the small train. The condition for generating Amperes force is that the conducting wire is in a magnetic field and the current direction and the direction of the magnetic field intensity are not parallel. The magnets attached to the poles of the battery provide a magnetic field, so how does the current generate? During the operation process of the small train, the magnet has always been in contact with the copper wire, plus the battery provides voltage, forming a continuous moving circuit. At this time, the current direction on the copper wire is not parallel to the magnetic field direction.Indeed, it is possible to generate an Amperes force, but this force acting on the copper wire cannot cause the little train to move. Therefore, we must change our approach. When current passes through a copper coil, it generates a magnetic field. On the perpendicular surface of the magnet to the forward direction, there is an equivalent circular current, and this is when the Amperes force is produced. This principle can be proven through experimental phenomena. In the experiment, only when two magnets with the same pole are attached to the ends of the battery will the little train move. The specific force is shown in the figure. The figure reflects the situation when two magnets with the N pole are produced horizontally to the right when the N pole of the magnet is produced horizontally to the right. The equivalent circular current of the left magnet is shown in the figure. Since the magnetic field strength on both sides of the electrically conductive coil is divergent and not parallel, according to the left-hand rule, a small section of the equivalent current is shown in the figure. The Amperes force in the horizontal direction has a left component. Similarly, the equivalent current of the right magnet is subject to Amperes force and also produces a horizontal left component. Therefore, the little train is subject to a force to the left and moves. When the two magnets are in the S pole position, the other conditions remain the same, that is, the direction of the coil current remains the same. Then, both sides produce Amperes force and have a horizontal right component.The magnet moves to the right.
