Why Do Induction Stoves Heat the Pan but Not the Cooktop?

💡 The Answer

• The stove generates a high‑frequency alternating magnetic field.
• The magnetic field induces eddy currents only in ferromagnetic pan bases.
• These currents heat the pan directly through resistive heating, not the glass surface.
• The cooktop stays cool because glass is non‑magnetic and non‑conductive.
