Which statement gives the relationship between the waves in the electric and magnetic fields in an electromagnetic wave?
They are in phase but perpendicular to each other in space.
What is the difference between electromagnetic induction and magnetic induction?
Electromagnetism is first discovered by Oersted. Electromagnetic induction first found by Michael Faraday. Electromagnetism is the phenomenon in which magnetism is produced when electric current flows in a straight wire. This is the conversion of electrical energy into magnetic energy. But electromagnetic induction is the phenomenon in which electric current is produced in a wire as it cuts the magnetic lines of force. Here in the presence of magnetic energy mechanical energy gets converted into electrical energy. The former is applied in fans, motors etc. The later is utilised in generators. In an electrical bell, electromagnetism plays an important role. In case of choke, electromagnetic induction serves in a nice way. Former has Biot-Savart law, Ampere's circuital law, Lorentz force law, Fleming's left hand rule, Right hand thumb rule. The latter has Faraday's laws, Lenz law, Fleming's right hand rule.
What is the relationship between electrical frequency and magnetic field speed for an ac machine?
What is the relationship between electrical frequency and magnetic field speed for an ac machine
Explain the difference between permanent and electromagnetic magnets?
In an electric magnet there is an ordinary metal used which when you run a current through it, induces a magnetic field, the permanent magnet (usually made of lodestone) contains particles which are already arranged in a manner that produces a magnetic field.
Why are some waves called electromagnetic?
Waves that are called electromagnetic are labeled as such because they are oscillations between electric and magnetic fields. Radio waves, visible light, and X-rays are examples of these types of waves.
What is the relationship between electricity and magnetisum?
The magnetic field will be perpendicular to the electric field and vice versa.More DetailAn electric field is the area which surrounds an electric charge within which it is capable of exerting a perceptible force on another electric charge. A magnetic field is the area of force surrounding a magnetic pole, or a current flowing through a conductor, in which there is a magnetic flux. A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.The relationship that exists between an electric field and a magnetic field is one of electromagnetic interaction as a consequence of associating elementary particles.The electrostatic force between charged particles is an example of this relationship.
Which statement gives the relationship between the waves in the electric and magnetic fields in an electromagnetic wave?
They are in phase but perpendicular to each other in space.
Are electromagnetic waves stronger than regular magnetic waves?
There is no such thing as a purely magnetic wave. The wave aspect of an electromagnetic wave comes from the oscillations between electric and magnetic fields.
Phase relationship between oscillating electric and magnetic fields?
nothing
What is the phase relation between oscillating electric and oscillating magnetic fields in an electromagnetic wave?
The fields are in time phase and space quadrature.
What is the difference between Transverse Electrical mode and Transverse Electrical Magnetic mode?
Transverse modes are classified into different types:TE modes (Transverse Electric) no electric field in the direction of propagation.TM modes (Transverse Magnetic) no magnetic field in the direction of propagation.TEM modes (Transverse Electromagnetic) no electric nor magnetic field in the direction of propagation.Hybrid modes nonzero electric and magnetic fields in the direction of propagation.
How is electromagnetic induction defined?
When there is relative motion between a magnet and a coil of wire, an electric current starts flowing in the coil. This phenomenon is called electromagnetic induction.When lines of a magnetic field cross the line of an conductor, electric current is induced in it.
When lines of force are cut by what you have electromagnetic induction?
When magnetic flux lines of force are cut by induced voltage between magnetic and electric currents. Electromagnetic induction is created.
The similarities between an electromagnetic wave and a magnetic wave?
There are no purely magnetic waves.
What did James clerk maxwell prove about visible light?
That it is a part of the electromagnetic spectrum
What is difference between of Electromagnet and Electric Magnetic Field?
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
Can an electromagnetic wave ever move?
This question is slightly back to front. It should perhaps read - can an electromagnetic wave ever not move ? The answer to this question would be no. Motion is absolutely central to the very existence of an electromagnetic wave. If the voltage between two conductors varies up and down, the electric field between them does the same. This changing electric field causes a changing magnetic field. The changing magnetic field causes a changing electric field, and so on ad infinitum. The net result of all this is an electromagnetic wave which propagates outwards at the speed of light.* If the wave were somehow prevented from moving it would cease to exist. * not really surprising, because light is itself an electromagnetic wave.
