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.

An electromagnetic field has both electric and magnetic components. Units of Weber and Tesla are used to measure magnetic flux and magnetic flux density, while Volts measure electric fields.
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.
A magnetometer is used to measure magnetic force in magnetic fields.
The unit of magnetism are: Weber for magnetic flux, Tesla for magnetic flux density and ampere per meter for magnetic field strength.
The induction magnetometer detects temporal variation of the geomagnetic field based on Faraday's law 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
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.
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
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.
if there is no magnetic induction there will be no electricity
A unit to measure magnetic flux.
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
Electro magnetic induction...................
For electromagnetic induction, you need a conductor moving in a magnetic field.
An electromagnetic field has both electric and magnetic components. Units of Weber and Tesla are used to measure magnetic flux and magnetic flux density, while Volts measure electric fields.
A Gauss Meter, or magnetometer, is an electronic device that is used to measure the strength of magnetic fields. Gauss Meters are commonly used to measure the strength of magnets and magnetic effects in electronics. They can also be used as metal detectors.
