Electromagnetism affects nanomaterials in various ways:
Electrical Conductivity: The electrical properties of nanomaterials can be significantly different from their bulk counterparts due to quantum confinement and surface scattering effects. Magnetic Properties: Nanomaterials can exhibit unique magnetic properties, such as superparamagnetism, which do not occur in bulk materials. Optical Properties: The interaction of light with nanomaterials can lead to phenomena like plasmonics, where the collective oscillation of electrons enhances electromagnetic fields.
