IttyBittyBit said:Yup. Here, have some levitating frogs. With a big enough magnetic field they could even levitate you.
cragar said:even photons and neutrinos , there is another thread going on in QM about the reaction to photons and neutrinos in the stern gerlach experiment
Magnetism is a fundamental force of nature that describes the interactions between objects that have magnetic fields. It is responsible for the attraction or repulsion between magnets and certain materials.
The three main types of magnetism are ferromagnetism, paramagnetism, and diamagnetism. Ferromagnetism is the strongest type and is exhibited by materials such as iron, cobalt, and nickel. Paramagnetism is weaker and is seen in materials like aluminum and platinum. Diamagnetism is the weakest and is found in all materials, but is usually overshadowed by the other two types.
Materials exhibit magnetism because they have unpaired electrons in their atoms. These unpaired electrons create tiny magnetic fields within the material, which align in the same direction when exposed to an external magnetic field, making the material magnetic.
No, not all materials can be magnetized. Only materials with unpaired electrons, such as iron, cobalt, nickel, and some rare-earth elements, can be magnetized. Other materials like wood, plastic, and glass do not have unpaired electrons and therefore cannot be magnetized.
Magnetism is used in many everyday objects, such as magnetic toys, speakers, and motors. It is also used in various industrial applications, such as in generators and electric motors. Additionally, magnetism is essential in medical technology, such as MRI machines, which use magnetic fields to create detailed images of the body.
