One of the most common electrical motor used in most applications which is known as induction motor. This motor is also called as asynchronous motor because it runs at a speed less than synchronous speed. In this, we need to define what is synchronous speed. Synchronous speed is the speed of rotation of the magnetic field in a rotary machine and it depends upon the frequency and number poles of the machine. An induction motor always runs at a speed less than synchronous speed because the rotating magnetic field which is produced in the stator will generate flux in the rotor which will make the rotor to rotate, but due to the lagging of flux current in the rotor with flux current in the stator, the rotor will never reach to its rotating magnetic field speed i.e. the synchronous speed.

SI unit of magnetic-induction?
Electromagnetic induction is the process of inducing electric current in a coil with the help of a magnet.Whenever a conductor is moved through a magnetic field, or the magnetic field fluctuates in strength (as with an AC electromagnet), a current will be induced in that conductor. Induction cooktops work by passing a large AC current through a conductor under the cooktop, creating a fluctuating magnetic field which induces an electric current through the cookware - heating the cookware by electrical resistance.The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.CommentFurther to the original answer, it is a voltage that is induced into a conductor, NOT a current.
What will happen to the world if there is no magnetic induction?
Without magnetic induction, Earth would lose its magnetic field, leading to increased exposure to harmful solar radiation, potential damage to the atmosphere, and disruption of electronic devices that rely on magnetic fields for operation. Life on Earth would be significantly different and face new challenges without the protection provided by the magnetic field.
What unit of measurement is used to measure an electromagnetic field and what instrument is used to measure that?
The unit of measurement for electromagnetic fields is typically the tesla (T) or gauss (G), depending on the strength of the field. Instruments used to measure electromagnetic fields include gaussmeters and magnetometers.
Describe magnetic line of induction?
Magnetic lines of induction, also known as magnetic field lines, are imaginary lines used to represent the direction and strength of a magnetic field. They always form closed loops, flowing from the north pole of a magnet to the south pole. The density of magnetic field lines indicates the strength of the magnetic field in a particular region.
Unit of magnetism are?
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
What is magentic induction and an example of magnetic induction?
The magnetic flux density at any point my be defined as the number of linese of magnetic induction passing through a unit area held a right angle to the lines at the point and is represented by the vectore
What does an induction magnetometer measure?
The induction magnetometer detects temporal variation of the geomagnetic field based on Faraday's law of magnetic induction.
What is the relation between weber and Tesla?
Weber is the unit used to measure the magnetic flux density, while Tesla is the unit of magnetic induction. They are related through the equation 1 Tesla is equal to 10,000 Gauss or 10,000 Weber per square meter.
What does a Tesla measure?
The SI unit tesla (T) for measuring magnetic flux density or magnetic induction (commonly known as the magnetic field ) was named in Tesla¹s honour at the Conférence Générale des Poids et Mesures, Paris in 1960.
Why is magnetic induction a vector quantity?
Magnetic field induction at a point is defined as the FORCE experienced by a unit north pole placed at that point. Since force is a vector quantity, manetic field induction also becomes a vector quantitiy.
What is flux density and how it is related to the number of lines of induction expressed in webers?
Flux density is the number of magnetic lines crossing per unit area in perpeendicular direction. It is named as manetic field induction, B. Unit is tesla or weber/m2 Unit for magnetic flux is weber in SI system. Fl
In what unit do you measure magnetic energy in?
asked this question on yahoo answers and this came up Answer 1 Magnetism generates a force and by itself it is not an energy. You generate energy by letting the magnetic force pull things together. In the same way that a hill is not an energy but if you roll down it you generate energy. To get back to the top you have to put the energy back in. Answer 2 Gauss is the unit of magnetic induction or magnetic flux density. I think this might be the answer to your question, but I am not sure
What scientific measurement was named after Nikola Tesla?
The tesla unit of electrical measurement (symbol T) is the SI derived unit of magnetic flux density, commonly denoted as B. One tesla is equal to one weber per square meter, and it was named in 1960 in honor of Nikola Tesla. The unit measures magnetic induction or magnetic flux density in the metre-kilogram-second system (SI) of physical units.

Does aluminum work on induction cooktops?
Yes, aluminum cookware does not work on induction cooktops because aluminum is not magnetic and induction cooktops require magnetic materials to generate heat.
What are the differences between induction and non-induction pans in terms of their heating capabilities and compatibility with induction cooktops?
Induction pans are compatible with induction cooktops because they are made of magnetic materials that respond to the magnetic field generated by the cooktop, heating up quickly and evenly. Non-induction pans, on the other hand, are not compatible with induction cooktops as they do not have magnetic properties and will not heat up efficiently on such cooktops.
What is necessary for induction?
For electromagnetic induction, you need a conductor moving in a magnetic field.
