1. Magnetismo
Nahum Gonzáles Obregón y Pedro Quispe Anca

2. ¿Qué es el
magnetismo?
El magnetismo es la capacidad de ciertos
materiales para atraer o repeler otros. Se
descubrió en la antigua Grecia con la
observación de propiedades magnéticas en la
magnetita, y Tales de Mileto notó su capacidad
para atraer objetos de hierro. A lo largo de la
historia, se ha desarrollado una comprensión
más profunda del magnetismo en términos de la
orientación de los átomos y los campos
magnéticos.

3. Propiedades del Magnetismo:
1. Atracción/Repulsión: Interacción entre polos
magnéticos.
2. Polaridad: Existencia de polos norte y sur en
imanes.
3. Imantación: Capacidad de retener magnetismo.
4. Conductividad: Algunos magnéticos son buenos
conductores.
5. Dominios Magnéticos: Átomos alineados en
regiones magnéticas.
6. Inducción Magnética: Convertirse magnético bajo
campo externo.

magnetismo:

4. Siempre hay dos polos

5. Tipos de magnetismo:
Existen varios tipos de
magnetismo, entre
ellos:
1. Ferromagnetismo
2. Antiferromagnetismo
3. Ferrimagnetismo
4. Paramagnetismo
5. Diamagnetismo

6. “La ley de polos magnéticos
dice lo siguiente: Polos
magnéticos iguales se repelen
y polos magnéticos diferentes
se atraen.”
—Ley de los polos
