)Electromagnetic fields are a type of field that is created by the presence of electrically charged particles. These fields consist of both electric and magnetic components and can exist in a vacuum or in a material medium.
Magnetic fields are created by the movement of electrically charged particles, such as electrons, within a material. This movement creates a force that can be detected as a magnetic field.
Electric fields are created by stationary electric charges, while magnetic fields are created by moving electric charges. Additionally, electric fields act on both electrically charged and uncharged particles, while magnetic fields only act on charged particles.
Yes, fields can be manipulated or controlled using various methods such as changing the strength of an electric current or using materials with specific magnetic properties. However, this manipulation is limited by the laws of physics and the properties of the materials involved.
There is ongoing research on the potential health effects of exposure to electromagnetic fields, particularly from sources such as power lines and electronic devices. However, current scientific evidence suggests that exposure to low levels of these fields is not harmful to human health.
