Why can an induction heating process heat magnetic material faster than non magnetic material?
To heat something by induction (which is and oscillating magnetic field), the material has to react to the magnetic field. As the magnetic field is made to oscillate, the molecules of the material are pulled and vibrated in sympathy with the field and their vibration energy increases.
Heat IS the vibration of molecules.
Thus induction heating will work on a magnetic material but will have no effect on a material that is not magnetically susceptible.

How can magnetism be induced in non-magnetic iron?
Iron can be demagnetised by heating for an extended period of time. _______________________________________________________________ You have to melt it and and allow it to re-solidify and it will be demagnetized. If you heat it to near melting and allow it to stay that hot for awhile then it will demagnetize of time (this is because bits of it will be hot enough to melt and demagnetize and that heat will disperse somewhere else to demagnetize a different spont). The temperature at which a ferromagnetic material, which is a material that retains an applied external magnetic field (like iron), loses its magnetization is called the Curie temperature.
What is magnetic line of induction?
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.AnswerThere is no such thing as a 'magnetic line of induction'. Induction is a process, by which a changing current induces (causes) a voltage into the same conductor or an adjacent conductor.A 'line' on the other hand, is imaginary and is simply a method of modelling a magnetic field in such a way that we can visualise its shape, rather in the same way that we use contour lines to show the shape of hills, etc.
What are methods of magnetisation and of demagnetisation?
De-Magnetisation: Place in a field of alternating current; usually produced by a solenoid, and remove slowly out of the field. Magnetisation: Swipe with one end of a magnet until the iron/steel bar is magnetised. You can use many magnets if you want to speed up the process. The strongest magnets are created by wrapping coils around the bars, and inducing alternating current in these wires using a power source.
When a magnet touch an iron nail does the nail becomes a temporary magnet?
The magnetic field would propagate through the material and extend itself for the length of the magnetic material in contact. As long as there is contact there is no pole present. When contact is broken the pole would be the opposite to the pole it was in contact with
What is demagnetisation?
Demagnetization refers to the process of reducing or eliminating the magnetism in a material. This can be done by subjecting the material to heat, applying an alternating magnetic field, or exposing it to a demagnetizing coil. Demagnetization is commonly used to reset magnetic tapes, hard drives, and other magnetic storage devices.
High frequency induction heating?
High frequency induction heating is a process that uses an alternating magnetic field to generate heat in a conductive material. This method is commonly used for applications such as hardening, tempering, and brazing of metals. The high frequency of the electromagnetic waves allows for rapid and efficient heating of the material.
What is the induction method of magnets?
The induction method of magnetizing materials involves exposing the material to a strong magnetic field, causing the magnetic domains within the material to align in the direction of the field. This process creates a magnet with north and south poles.
What is induction heating?
Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal.induction heater including high frequency induction heating machine and middle frequencey heating machine. Induction heating applications for an induction furnace include induction welding, induction brazing, induction hardening, induction melting, quenching, forging, soldening, induction annealing and other forms of heat treatment. Induction heating is often used to heat graphite crucibles (containing other materials) and is used extensively in the semiconductor industry for the heating of silicon and other semiconductors. Induction heating can produce high power densities which allow short interaction times to reach the required temperature. That translates into lots of energy transferred into a material right now, with a very rapid rise in temperature.
What is vacuum induction melting?
Vacuum induction melting (VIM) is a metal process to use electromagnetic induction heating principle to melt the metal under vacuum conditions. In the electromagnetic induction heating process, the induction coil of induction heater will produce eddy current in order to melt the metal. This induction melting process can be used to refine high purity metals and alloys. If you want to learn more, please Visit gslipai. com or sent an email to lipaiheating@gmail.com.
What is a demagnetizing action?
Demagnetizing action refers to the process of reducing or removing the magnetism from a material. This can be done by subjecting the material to a strong alternating magnetic field or heating it above its Curie temperature to randomize the magnetic domains and reduce the overall magnetization.
What is the process by which electric current is generated by placing a wire in a magnetic field?
When a wire is placed in a magnetic field and moved relative to the field, an electric current is induced in the wire due to electromagnetic induction. This phenomenon occurs due to the interaction between the magnetic field and the moving electric charges within the wire, creating an electromotive force (EMF) that drives the current flow.

What is the definition of electro magnetic induction?
Magnetic induction is the process in which an item is magnetized by an external magnetic field. The force of the fields comes from the poles of the magnet to produce the magnetism. The process is also called magnetic flux density.
What is the process by which electric current is generated by placing a wire ina magnetic?
This process is called electromagnetic induction. When a wire is moved within a magnetic field or a magnetic field is changed around a wire, it creates an electric current in the wire. This is the underlying principle behind how electricity is generated in things like generators and electric motors.
