Induction Stove
Working Principle
Uses electromagnetic induction (Faraday's Law)
AC through copper coil → changing magnetic field → eddy currents in vessel → Joule heating
Only the vessel heats, not the surface
Scientific Laws
Faraday's Law, Lenz's Law, Joule's Law (H = I²Rt)
Advantages vs Limitations
Advantages
85–90% efficient
Needs ferromagnetic cookware
No open flame – safe
Needs stable electricity
Easy to clean
Limitations
Higher initial cost
Precise temperature control
EMI risk for pacemaker users
