Induction hob screeching

    I am new to induction hobs and just got a new one (with very little research I should add).

    Just started using it this week and I am a bit worried by the sound it makes on high power. Can those in the know check out the video I took and tell me if this is normal. Thanks

    Yeah I'm pretty sure ours doesn't do that.

    Is the pot stamped underneath as suitable for induction.

    Also what size cable was used to feed the supply.

    Pot shouldn't be an issue, this is them: https://www.amazon.co.uk/gp/aw/d/B00J7GVM9G?psc=1&ref=ppx_pop_mob_b_asin_title

    Will have to check cable, but all seems to work fine

    Ours makes a noise a bit like that too. It only happens with a particular set of stainless steel pots and it’s worst when boiling water. It stops when you move the pot onto the centre of the “ring”. Also interested to know if others experience this.

    I've had induction hobs for many years and they all do that. It's being caused by the larger stainless steel pot amplifying a small vibration a bit like a bell.

    They're not totally silent, especially big bigger pots.

    Mine doesn't make anything like that amount of noise. Even on the Power setting it only makes a barely audible him.

    It depends on the shape and materials in the pot.

    If you've a very large, thinner pot it just reverberates like a bell. The hob is inducing oscillating electrical currents in the bottom of the pot that can result in vibrations, particularly as the material comes up to temperature.

    Effectively it's a bit like the way an induction coil on a speaker causes the diaphragm to vibrate when it interacts with the magnet, it's just a lot cruder as it's just an induction coil and a large pot.

    The higher power settings will also tend to make that noisier.

    If you try a thicker bottomed pot it will likely not make as much noise.

    Suitable for induction doesn't mean much more than it heats on an induction hob i.e. it's made from ferrous metal.

    If you look for example at Miele's website, they're selling pots that are designed not to be noisy. https://www.miele.ie/domestic/1862.htm?info=200018955-ZST

    Also beware of some of the aluminium pots that have a coil of metal in the bottom of them to make them "induction compatible" as only that coil or plate will heat and you can get weirdly uneven cooking. A thick bottomed, flat stainless steel or cast iron pot / pan works best.
