In the educational institution where I work, before the coronavirus, many academic activities were carried out, one of which caught my attention, was that of creating electricity to light a light bulb with a magnet, this caught my attention. Professor Joan Ferrer from the Department of Physics explained why it occurred, when a metal cable crosses the magnetic field of a magnet, the wire is charged with electric force and makes electrons that produce energy travel through it the rest would be to channel it, for which I carry out an experiment
For this I use:
Insulating tape
One and a half meter of copper wire
A pliers for cutting metal
A light bulb or small voltage LED
A large round magnet
A long plastic cylinder, such as a large syringe, cannula, or injection
The teacher wrapped the copper wire around the cannula leaving one end at the beginning that is at least 15 cm long, covered the largest area of the outside of the syringe with the wire.Once you're done, leave one end of the wire at the end of 15 cm and cut with the metal clip
To prevent the coil from falling apart, take the electrical tape and wrap it around the wire until the entire surface is covered.
Remove the enamel from the ends of the cable by scraping it with the help of the pliers. You can also use a lighter, tinder box, or lighter. Be careful because the wire gets hot
It's time to grab the bulb and glue the wires to the connector. To do this, take your small LED bulb and connect one end to one of the contact points. Secure with electrical tape and do the same with the remaining end and point of contact
Insert the magnet into the cannula and use the stopper to close the inlet, but only slightly
Turn off the lights in the room where you are. Holds the bulb in one hand and the syringe in the other
Start beating the syringe over and over again, as fast as you can. To my surprise, if I turned on the light bulb
Luz con Iman
En la institución educativa donde trabajo, antes de coronavirus, se realizaba muchas actividades académicas una de las que llamo mucho mi atención, fue la de crear electricidad para encender una bombilla con un iman, esto llamo mucho mi atención. El profesor Joan Ferrer de la Catedrá de Fisica me explico porque se producía, cuando un cable metálico se cruza con el campo magnético de un imán, el alambre se carga de fuerza eléctrica y hace que, a través de él, viajen electrones que producen energía eléctrica, lo demas sería canalizarlo, para lo cual realizo un experimento
Para ello empleo:
Cinta aislante
Un metro y medio de cable de cobre
Una pinza para cortar metal
Una bombilla o LED de pequeño voltaje
Un imán grande redondo
Un cilindro plástico largo, como una jeringa, cánula o inyección grande
El profesor enrolló el cable de cobre alrededor de la cánula dejando un extremo al principio que tenga al menos 15 cm de largo, cubrio la mayor área del exterior de la jeringa con el cable Una vez que termines, deja un extremo de cable al final de 15 cm y corta con la pinza de metal
Para que la bobina no se deshaga, toma la cinta aislante y enróllala alrededor del cable hasta cubrir toda la superficie
Remueve el esmaltado de las puntas del cable raspándolo con ayuda de la pinza. También puedes utilizar un mechero, yesquero o encendedor. Hazlo con cuidado porque el cable se calienta
Es tiempo de agarrar la bombilla y pegarle los cables al conector. Para ello, toma tu bombilla LED pequeña y conecta un extremo a uno de los puntos de contacto. Asegúralo con cinta aislante y haz lo mismo con el extremo y punto de contacto restante
Introduce el imán dentro de la cánula y usa el tapón para cerrar la entrada, pero solo un poco
Apaga las luces de la habitación donde estés. Agarra la bombilla con una mano y la jeringa en la otra
Comienza a batir la jeringa una y otra vez, lo más rápido que puedas. Para mi sorpresa, si encendio el bombillo
