Llegó rápidamente (10 días a Eslovenia) y es exactamente como se describe. Es muy bueno para demostraciones en el aula.

Es lindo: pegue los imanes en los extremos de una batería AAA y véala volar a través de la bobina. (Si no es así, intente invertir el imán en un extremo, o ambos si eso no ayuda). Si coloca los extremos de la bobina uno frente al otro, la batería seguirá funcionando en círculos. No puedo esperar para enseñarle esto a mis nietos...

Estos tres juegos son de un nuevo pedido, dado que en un pedido anterior pedí dos más y me gustaron mucho. El efecto es idéntico al del vídeo que pone el vendedor en la página. Lo recomiendo al 100%

Al principio no me funcionó. Incluso pensé en hacer una consulta al vendedor. Pero probé a cambiar la polaridad de los imanes de uno de los polos y el resultado fue fantástico. Todo funcionó a la perfección. La verdad es que tuve que emplear los imanes de dos juegos que compré, por ello echo en falta duplicar la cantidad de imanes por juego, para que el resultado sea como el del vídeo de demostración que pone el vendedor. ¡Ah! es importante que la pila sea nueva y alcalina (no vienen incluidas, pero es fácil de encontrar en cualquier tienda). Le pongo 5 estrellas al vendedor, porque no puedo poner más, pero agradezco mucho la iniciativa de vender este tipo de juegos, pues a los niños les entusiasma. Es un lástima no poder poner un vídeo, pues se vería mejor el efecto. Como sugerencia a ALIEXPRESS, pediría que implemente la subida de archivos de vídeo.

¡Super juguetes para niños que disfrutan aprendiendo! La Construcción del experimento es simple y transmite los conceptos básicos de electromagnetismo. Sin embargo, lamentablemente faltaba la batería, lo que fue un poco decepcionante. Todavía recomendado para los pequeños científicos

No había baterías e imanes para baterías AA, había 4 imanes para baterías AAA y menos. Y así funciona la física.

Funciona a la perfección, muy agradable para mostrar a los niños. No venía con batería pero no hay problema por su bajo precio. Importante saber que necesita batería AAA no.
