Video report: An introduction to induction cooking

Now that induction cooking appliances are within reach of the average consumer, homeowners are more curious about their capabilities. Induction ranges use an electromagnetic field that speeds cooktop heating. Some cost $2,500 or more but we found models that sell for hundreds less and that also aced our cooktop tests.

If you haven't bought a new range or cooktop in recent years, mastering the electronic controls can involve a learning curve. One maker claims that they're "as easy to use as your MP3 player," but we suggest keeping the owner's manual at hand. And as with all induction models, you'll need magnetic cookware for the induction elements to work properly.

Speed is another distinct advantage of induction cooking: In our tests, the fastest induction elements brought six liters of water to a near boil in just eight minutes, compared with the 12 to 16 minutes for most electric and gas models.
