You played a magnet? Do you want to make an electric magnet， this can be an easy job to suck up the nails.

Assembly:

Winding enameled wire is the key to ensuring a magnet works， 6 meters of the enameled wire wrapped in patiencebar iron and U iron intermediate， the current through the U coil and strip coil can produce magnetic field. Electric current is bigger， stronger magnetic.

Maglev train in life is to use the principle of an invention.

Product description:

To understand the Ampere rule and its application.

To understand the role of iron in electromagnet;

To understand the role of iron in electromagnet;

Understanding the relationship between the magnetic intensity and the current size and the number of turns of the coil.

The children finish assembly process parents with children learning situation， heuristic education.

To explore the boy is exploration， he is not a simple science， but involves a variety of subjects， such as physics，chemistry， astronomy， mathematics， and its visualization， modeling， standardization. Objective is to commence from the interest， find the children's interest in learning， so as to effectively guide， finally let the children interested inlearning. To feel the real world with the scientific thought of splendid， the virtual world and let the children stay away from computer games.

Reminder.

Please note that when using the metal sharp edge. Don't will lead into the household outlet， to prevent the risk of electric shock. In the use of some small accessories products don't let the children under the age of 3 to. Please parent child carefully read the product description instruction before using this product.
