    i miss the days of playing with a 25KW industrial heater....

    old guy in the shop thought CF would be a good prod (we brazed carbide tools)

    "you ready for this mate?"

    BANG. no more carbon fibre rod!

    CF is highly conductive!

    that thing would vaporise a 1.5 inch bar with a 2 inch, 4 turn coil.

    sir with all your respect i want to say that i sometimes watch your videos because the title of your video is very attractive , But when i watched it within 10 to 15 seconds i totally lost my interest, Believe me its happen all the time trying to watch any of your videos. May be i am stupid. But i some times i think not every body is a professor or a scientist like you so why you make a simple thing Harder, Look man i am not a engineer i don't have any back ground in electronics but i can make a induction heater in two hours may be three...How i learn that?
    Every thing i learn and everything i can make or trying to make its all from you guys who make beautiful videos and they explains that subject very easy and understandable as possible..Look man don't misunderstand me , People like us searching TheXvid for learning something what we can't learn as this Quickly and Easily without talented guys like you...So i Respect you and very Grateful to you guys...
    I watch your videos many years from now that i can't remember but never can't watch it till the End.. I DON'T USUALLY COMMENTS ON TheXvid BUT TODAY MY HEART WANTS TO WRITE SOME THING....I HOPE YOU UNDERSTAND AND ALSO FORGIVE ME FOR THIS LONG COMMENTS......take care...

  • A-Triangle

    Will increase of frequency be beneficial for inductive heating ?
    Or is the frequency determined by the heating coil ?

    • A-Triangle
      A-Triangle 18 days ago

      @Mark Krützmann Thanks for the thorough answer.
      I asked, because electicity costs money.
      So, a higher frequency, needs less current, for the same effect.
      In fact, a LC circuit will generate a frequency, between the coil and capacitor.
      This will keep going, for a while, even when you do not power the circuit.
      Of course, this effect will disspate quickly, when put you some material
      in the coil. However, you might just need to power the circuit, with
      small pulses, to keep it going.
      I am just brainstorming here, to see how this can be made
      energy efficient.

    • Mark Krützmann
      Mark Krützmann 19 days ago

      The frequency is determined by the capacitors and the working coil. You can easily change the capacitance to change the frequency or wind another coil, but bear in mind that the inductance changes heavily when ferromagnetic material (like the iron rod) is inserted.
      As for the effects of a higher frequency: yes, it does speed up the heating process as the hysteresis loss happens more often. But! the higher the frequency, the higher are effects like the skin effect and you are effectively heating just the outer layer of your iron rod at some point.
      So, there is an optimum for a given iron diameter. Another problem is that the coil will have losses, too. This becomes very hard to handle quickly and you have to start watercooling the coil (use a copper tube).
      More current obviously also helps, so just increasing the voltage will heat up your stuff faster as well. You do need a beefier supply for that to work than @GreatScott though.

    if we use tesla coil for voltage will it possible to boil water with that??
    if we use battery then how much energy required by induction cook top

    • Overloader7
      Overloader7 Month ago

      Problem is not voltage - current is. Tesla coil while having high voltage, also have high resistance, so current will be quite low

    Hey, i just tried to build a circuit following the schematic of your circuit but i always get a type of short circuit... Im not getting my powersupply to get out of the current limitation mode which suggests a short circuit. Do you have any idea where this could come from? I double checked the mosfets for pin errors etc but the circuit itself seems to be exactly the one you showed in the video. Thanks in advance!

    Non professional don't understand this experiment it is related to electrical engineering ' hub of knowledge. When current is pass in the turns of a coil that produces magnetic flux likes with itself is known as self inductance or solenoid. The magneting force cut air which is to be equal to absolute permeability multiplied by magnetic field.
