Magnetismo de la Tierra by Marta Baron on Prezi

The grape will be repelled by the magnet and begin to move slowly away from the magnet. If a magnet is brought toward a diamagnetic material, it will generate orbital electric currents in the dia,agnetico and molecules of the material.

Helium, bismuth, and water are examples of diamagnetic substances. Every electron is therefore a very tiny magnet, because electrons carry charge and they spin.


Existen cinco grupos de elementos donde ocurre esto. Atoms and molecules in which all of the electrons are paired with electrons of opposite spin, and in which the orbital currents are zero, are diamagnetic. Push one grape onto each end of the straw. No se ve afectado por los cambios de temperatura.


Two large grapes Drinking straw Film canister with lid Push pin Small knife or razor blade Neodymium magnet. The diamagnetic force of repulsion is very weak a hundred thousand times weaker than the ferromagnetic force of attraction. The grape will also be repelled by the other pole; the grape is repelled by both poles of the magnet.


The grape is repelled because it contains water, which is diamagnetic. This law states that when a current is induced by a change in magnetic field the orbital currents in the grape created by the magnet approaching the grapethe magnetic field produced by the induced current will oppose the change.

Find the center of the drinking straw and use the knife to cut a small hole, approximately 0. Push me a grape. Balance the straw with the grapes on the point of the push pin; the point of the pin goes through the small hole on the straw.

This behavior is predicted by a law of physics known as Lenz’s Law. Turn the magnet over and bring the other pole near the grape. Do not touch the grape with the magnet.

Diamagnetic materials, however, are repelled by both poles of a magnet. These materials are ferromagnetic, and are strongly attracted to magnetic poles. Ferromagnetic materials, such as iron, are strongly attracted to both poles of a magnet. Insert the push pin through the underside of the film canister lid and put the lid on the canister so that the point of the pin is sticking out. Additionally, the motion of an orbital electron is an electric current, with an accompanying magnetic field.


Electrons in these materials orient in a magnetic field so that they will be weakly attracted to magnetic poles. Atoms and molecules that have single, unpaired electrons are paramagnetic. Diamagnetic materials are repelled by magnetic poles.

When an electric charge moves, a magnetic field is created. A grape is repelled by both the north and south poles of a strong rare-earth magnet. Pull the magnet away and let the grape stop its motion.

Bring one pole of the magnet near the grape. Paramagnetic materials, such as aluminum, are weakly attracted to both poles of a magnet.

Water, the main component of grapes, is diamagnetic. Hydrogen, lithium, and liquid oxygen are examples of paramagnetic substances. You can also use the hot tip of a soldering gun to melt a hole. In atoms of iron, cobalt, and nickel, electrons in one atom will align with electrons in neighboring atoms, making regions called domains, with very strong magnetization. Ver todo mi perfil. The magnetic fields associated with these orbital currents will be oriented such that they repelled by the approaching magnet.
