6 FAQs about [Why is the electromagnet an energy storage element]
What is the energy storage capability of electromagnets?
The energy storage capability of electromagnets can be much greater than that of capacitors of comparable size. Especially interesting is the possibility of the use of superconductor alloys to carry current in such devices. But before that is discussed, it is necessary to consider the basic aspects of energy storage in magnetic systems.
Can energy be stored in a magnetic field?
Textbooks say that in a capacitor or inductor, energy is stored in a electric or magnetic field. How can energy be stored in a field? Mathematically it can be proved but I am not able to feel what it means physically.
What is energy stored in a field?
Energy stored in fields = the total energy required to assemble the fields It takes energy to bring the charges to specific positions to assemble the field, and when you let everything go, the charges will just fly apart. The energy you stored in the field becomes the kinetic energy of the charges once you let them go.
Does an electromagnet wave have energy?
You have learnt that an electromagnet wave comprises an electric field and a magnetic field oscillating mutually at right angles to one another. Being a wave it carries energy and so an electromagnetic wave must have energy associated with it. Where is that energy stored?
What is an electromagnetic field?
An electromagnetic field (EMF) is caused by electrically charged objects and influences the behavior of materials or charged particles around it. The total amount of energy of the field and the materials it affects is called electromagnetic field energy.
What is affected by an electromagnetic field?
Electromagnetic field is caused by electrically charged objects, that influences the behavior of materials or charged particles around the field. The total amount of energy of the field and the materials it affects is called electromagnetic field energy.
