IMANES PERMANENTES, CAMPO MAGNÉTICO Y LÍNEAS DE FUERZA

STRAIGHT AND HORSESHOE-SHAPED MAGNETS EXPERIMENTAL WORK TO OBSERVE THEIR PROPERTIES By moving a steel ball attached to the bottom of a straight magnet, it is observed that the magnetism resides at the ends, called the MAGNET'S POLES. As the ball approaches the center of the magnet, it detaches. The center of the magnet is called the NEUTRAL OR NULL ZONE. Using flat straight magnets, observe the shape of the magnetic field and the configuration of the lines of force by scattering iron filings. In the central part, there is no agglomeration of iron filings. Null zone, there is no magnetism. Observe the configuration of the lines of force and the magnetic field by placing two magnets facing each other with their poles. By scattering iron filings, With equal poles, it is observed that the lines of force repel each other. With different poles, it is observed that the lines of force come together. Horseshoe magnets. It is observed that the lines of force connect the magnetic poles. THE MAGNETIC SPECTRUM. This refers to the visualization of magnetic fields using iron filings. Making the invisible visible. COULOMB'S LAW of magnetism. Attractions and Repulsions. Like magnetic poles REJECT each other. Unlike poles ATTRACT each other.
