Induction Stove

As all we know,induction stove works on the principle of electromagnetic induction.Thus an emf is induced in the vessel and eddy current flows through the vessel.
Since the vessel is made of ferromagnetic material (high resistivity) larger amount of heat (H=I^2 R)is generated.
What will happen if a human body comes into contact with this high resistive vessel??? Won't the human body resistance be parallel with the vessel (net resistance reduces) and human be exposed to shock????

Definetly we are going to feel the shock. As soon as we come in contact with the high resistive body a low resistive path(When compared to ferromagnetic material human body has less resistance) to the ground is found so that current starts flowing through the body which inturns makes us to feel the shock!!!

Capacitor and condenser both are different electronic components. An A.C capacitor store 220v AC voltage for a while but on the other hand D.C condenser reduce the power voltage.

The excessive heat will harm the human but nothing about the shock will happen because there is no path for the current to go through and the current that is making heat is eddy current that happens on cores not on any material + the core doesn't have voltage so when human touches it there isn't Voltage difference between the two to make current flows so its about the heat

The parameter responsible for heating in Ind Cooker is current (eddy). Ferromagnetic material, although high resistance compared to Cu or Al have much lesser resistance compared to human body. hence, eddies would rather love to travel though the metallic frying pan instead of fleshy human body.

Folks please tell me which has high resistance.Is it human body or ferro magnetic material.??

Ferromagnetic material is higher

Human body under dry condition has much higher resistivity compared ferromagnetic material.
