he electromagnetic stirrer utilizes the principle of a linear motor and differs from the conventional mechanical and decompression types as it is a noncontact stirrer in which no part touches the molten metal. As shown in the diagram, a coil installed at the bottom of the furnace generates a moving magnetic field (H) if a 3 phase AC voltage is applied to this coil (inductor). Electric power force is generated in the molten metal due to the action of the magnetic field (magnetic flux) and causes induction current (I) to flow (Fleming's right hand rule). This current then acts with the magnetic field of the inductor to induce electromagnetic force (F) in the molten metal according to Fleming's left hand rule. As this thrust moves in the direction of the moving magnetic field, the molten metal also moves. In other words, an stirring action is applied. Furthermore, as this thrust has components in the horizontal direction and in the vertical direction, the molten metal flows diagonally upwards and results in a uniform temperature in both the top and bottom layers of the molten metal.
The function of a stirrer is to agitate liquids for speeding up reactions or improving mixtures. The picture on the left is a magnetic stirrer used with hot plates. The picture on the right is a typical glass stirrer used in beakers or test tubes.
A magnetic stir bar is used to stir a mixture on a stir plate. The stir plate contains a magnet that spins, causing the magnetic stir bar to spin and stir the mixture. Many hot plates also have this feature built in.
a) Stirring a solution with the magnetic stirrer
b) Simultaneously heating the same solution
A stir plate has a revolving magnetic field which forces the stir bar to spin and stir whatever liquid you have.
A magnetic sitter is a device used in a laboratory that employs a magnetic field to cause a stir bar immersed in a liquid to spin very quickly - stirring it.
A magnetic stirrer is used when mixing water and sulfuric acid. Depending on the size of the stirrer is what determines how much of the liquid you can mix.
The principle that Bullet Train work on is Magnetic levitation and magnetic suspension. . .
Manipulation of the radio magnetic spectrum.
principle of a totalstation
same principle as induction motor,rotor chases the rotating magnetic field.
The main principle is that electricity could be sent wireless and he proved it.

synchronous generator is similar to the principle of laws of electro magnetic induction that is "whenever the magnetic flux linking in a conductor that time emf is induced at the ends of the conductor "
because working principle of both the things are same.The motor converts electrical energy in to mechanical via magnetic induction and generator do the exact opposite of this.And yes,you should use 'electricity generator' not only 'generator'.

Possibly, however I cannot see any function that it would serve.
The principle of magnetic recording was first developed in 1893 by a Danish inventor, Valdemar Poulsen

Magnetic separation is technique used in metallurgyfor the concentration of ore particles. The principle of this method is that the magnetic ore particles can be separated from non magnetic impurities (gangue) or viceversa.
What is the working principle of venturimeter?
The working principle of these instruments is same as that of the d'Arsonval type of galvanometers, the difference being that a direct reading instrument is provided with a pointer and a scale. The basic principle of this device is the interaction of magnetic field of the compass (a permanent magnet) and the field around the conductor (a simple electromagnet)
To ensure the solution is uniformly heated and the reaction is reacted overall
A working principle is a regulation or rule that is used so that work can be done. This is a general phrase that can be used in any circumstance from the working principle of a motor, to the working principle of a solar cells.
