Electromagnetic Field
1. What is the source of electromagnetic field?
Electromagnetic fields are generated by natural phenomena like the Earth’s magnetic field but also by human activities, mainly through the use of electricity.
2. Can you give some examples which generates electromagnetic fields ?
Mobile phones, power lines and computer screens are examples of equipment that generates electromagnetic fields.
3. What is electromagnetic field made of?
Electromagnetic field made of charged particles ,such as electrons and protons. These create electromagnetic fields when they move, and these fields transport the type of energy we call electromagnetic radiation, or light.
Properties of Electromagnetic Field
In terms of Electrical engineering, Electromagnetic Field plays an important role in describing the motion of electric charge. When an electric charge moves in free space electromagnetic field generated. The electromagnetic field refer to the combination of a magnetic field and an electric field. Electromagnetic field, a property of space caused by the motion of an electric charge. A stationary charge will produce only an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. Electric and magnetic fields are both components of an electromagnetic field. The electromagnetic field is a combination of electric and magnetic field of force, they are dispersive in nature.
