hello
which is the lightest material that electromagnetism can set it in motion?
thanks!

You won't get much power transfer without a mechanical connection or very large and heavy magnets.

Depends on the details of the setup, maybe all together.physior said:large and heavy magnets or high currents and high voltages?
mfb said:@Dinis Oliveira: Free neutrons are unstable, so in normal matter they are always bound in nuclei with protons, and then you have charged objects around again. In addition, neutrons contain quarks, and those are charged.
mfb said:They decay (to proton+electron+neutrino).
Electromagnetic materials are substances that can interact with electromagnetic fields, either by generating their own fields or by altering the properties of an existing field. These materials are used in a variety of applications, including communication devices, medical equipment, and energy generation.
Electromagnetic materials have a wide range of properties, depending on the specific material and its composition. Some common properties include electrical conductivity, magnetic permeability, and dielectric constant. These properties determine how the material will interact with electromagnetic fields and can be manipulated for different purposes.
Some common examples of electromagnetic materials include metals such as copper and aluminum, which are good conductors of electricity, and ferromagnetic materials like iron and nickel, which are able to produce strong magnetic fields. Other examples include semiconductors, superconductors, and insulating materials like plastics and ceramics.
Electromagnetic materials are used in a wide variety of technologies, including radios, televisions, computers, and smartphones. They are also essential in medical equipment such as MRI machines and in renewable energy technologies like solar panels and wind turbines. The properties of these materials allow them to efficiently transmit, receive, or manipulate electromagnetic waves, making modern technology possible.
The study of electromagnetic materials falls under the field of material science and engineering. Scientists and researchers use a variety of techniques and tools, such as spectroscopy and microscopy, to study the properties and behavior of these materials. They also use theoretical and computational models to understand and predict the behavior of electromagnetic materials, allowing for the development of new and improved materials for various applications.
