Microwaves are detected by a ghosts b electromagnetic fields c micowave ovens d cooling systems?
None of the above. * Ghosts are not a part of physics. * Electromagnetic fields in a static sense do not exist. Electromagnetic radiation does; it consists of a changingelectric field which causes a changing magnetic field which causes a changing electric field which causes . . . and so on forever. Electromagnetic radiation moves off at the speed of light ; it has different properties depending on how fast the fields are changing, including radio waves, microwaves and light.. * A microwave oven generates microwaves. Microwave radiation cannot "detect" itself. * Cooling systems are designed and built to cool. They can't detect anything, including microwaves.
Why does the sun have so many magnetic fields?
The sun does not have 'so many magnetic fields.' It has 1 magnetic field that varies according to the distance from the sun.
What is a current in a circuit measured in?
ampsAnswerElectric current is measured by means of an ammeter. Electric current is expressed in amperes (symbol: A), which is defined in terms of the magnetic effect of an electric current -i.e. the force between two, parallel, current-carrying conductors.
What substance can solar winds not penetrate?
Just about any solid object will stop the solar wind. A sheet of aluminum foil would be effective. More important is the idea that magnetic fields, like planetary magnetic fields, deflect the solar wind. (This though a magnetic field is not a substance, per se.) Earth's magnetic field does a fine job of this.
What is the current theory of the origin of magnetic fields?
Moving electric charges generate a magnetic field. This isn't a theory, it's a simple demonstrable fact. There really isn't a theory why this is true, it's just something that istrue."Spinning" charges also generate a magnetic field. I've got "spinning" in quotation marks because this applies also to charges that aren't actually physically spinning, but have a non-zero quantum spin number.
A wave that consists of changing electric and magnetic fields is called?
An electromagnetic wave.
What is a wave that consists of changing electric and magnetic fields called?
Sound wave
How are changing electric and magnetic fields related?
Changing electric fields create magnetic fields, and changing magnetic fields create electric fields. This relationship is described by Maxwell's equations. The two fields are interdependent and can propagate through space as electromagnetic waves.
What consists of changing electric and magnetic field s?
Changing electric and magnetic fields consist of producing electric currents, electromagnetic waves, or inducing magnetic fields in a given medium. This change can be observed through various phenomena, such as electromagnetic induction, electromagnetic radiation, or the propagation of electromagnetic waves.
What is a wave that consists of changing electric and magnetic fields that vibrates at right angles to each other?
Electromagnetic wave
What is a wave that consists of electric and magnetic fields?
electronic wave
What causes electric magnetic wave?
Electromagnetic waves are caused by changing electric fields which create magnetic fields, and changing magnetic fields which create electric fields. These waves propagate through space at the speed of light and carry energy. They are produced by accelerating charged particles or by oscillating electric currents.
Will changing the electric field will have no effect on the magnetic fields of a body?
Changing the electric field in a region can induce a magnetic field according to Maxwell's equations. This is known as electromagnetic induction. So, changing the electric field can indeed have an effect on the magnetic fields of a body.
Why is a vibrating electric field an example of an electromagnetic wave?
A vibrating electric field produces a changing magnetic field, which then generates a changing electric field and so on, creating a self-propagating wave. This wave consists of oscillating electric and magnetic fields perpendicular to each other and to the direction of wave propagation, thus exhibiting the characteristics of an electromagnetic wave.
Do Electromagnetic waves consist of changing electric and magnetic fields?
Yes, electromagnetic waves consist of oscillating electric and magnetic fields perpendicular to each other. As the electric field changes, it generates a magnetic field, which in turn generates a new electric field, creating a self-sustaining wave propagating through space.
When a blank wave that is produced by a vibrating electric charge is an electromagnetic wave?
When a vibrating electric charge produces a changing electric field, it in turn generates a changing magnetic field, leading to the creation of an electromagnetic wave. This wave consists of oscillating electric and magnetic fields that propagate through space at the speed of light.
What do electromagnetic travel through?
changing electric and magnetic fields {[((apex))]}
