How Induction Cooktops Work

How Induction Cooktops Work
2

• Induction cooking is based on an electro-magnetic
  field creating energy which heats the base of a
  pan positioned on the cooktop.
• The electro-magnetic field is activated when
  material containing iron (ferrous material) comes
  within range of the inductors beneath the cooktop
  surface.

Introduction

• Induction cooktops boast speed surpassing
  electric, temperature response rivaling gas, and
  safety and cleaning ease that beat out
  glass-and-ceramic-top stoves.
• Pans need to contain ferrous material for
  induction to work. Full stainless steel,
  aluminium, copper, terracotta or pyrex don't
  contain ferrous material, so theoretically they
  won't work.

Benefits of cooking with an induction cooktop
Efficient Induction cooking uses 90 of the
energy produced. Induction recognizes the base of
cookware, directly heating only the diameter of
the pot, so very little energy is wasted.
8
Safer There are no open flames and the surface
remains cool to the touch Quicker Heating and
adjustments are immediate, saving you up to 50
of the cooking time when compared to more
traditional methods Even Heating Hot spots and
rings are avoided because the bottom of your
cookware heats uniformly Easy Cleaning The
surface is flat and smooth spills and overflows
do not stick to the cooktop, so they can easily
be wiped away

Electromagnetic Induction

• Electromagnetic induction occurs when a circuit
  with an alternating current flowing through it
  generates current in another circuit simply by
  being placed nearby.
• An alternating current is the kind of electricity
  flowing through power lines and home wiring, as
  opposed to a direct current, which we get from
  batteries.

10
Look at a few principles linking magnetism and
electricity

• Every electric current has a magnetic field
  surrounding it.
• Alternating currents have fluctuating magnetic
  fields.
• Fluctuating magnetic fields cause currents to
  flow in conductors placed within them, which is
  also known as Faraday's Law.

Heating Induction Cooktops
Induction cooktops work the same way Coils
located just beneath the cooktop's elements carry
an alternating current, creating a changing
magnetic field.

Induction Cooktops Pros and Cons
Induction cooktops work, you're probably
wondering what makes them any better or worse
than cooktops with radiant elements, such as
electric coils, gas burners or glass-ceramic
stovetops.

Some of the pros and cons of induction cooktops
Cooking Experience Induction cooktops heat 25-50
percent faster and distribute heat more evenly
than radiant stovetops, and they offer quick,
fine temperature adjustment. Safety and
Cleaning Cooler surfaces and no open flame to
ignite grease, induction cooktops are safer and
easier to clean than their radiant
counterparts. Cost vs. Efficiency Prices start
at 1,800 and go up to about 3,500, compared
with 550 - 750 for top-tier electric cooktops
and 650 - 1,200 for gas.

Buying an Induction Cooktop Tips
Try before you buy Some manufacturers offer
cooktops that have induction elements alongside
radiant elements, or you can test drive the
technology with a portable unit for less than
200. Buy a model designed specifically for home
use Induction cooktops were originally designed
for use in industrial and restaurant
kitchens. Know what you're getting into If
you're replacing a stove or remodeling an
existing kitchen, be sure that your wiring,
voltage and amperage can handle the load. Ask an
electrician Power grids fluctuate, and even
modern wiring doesn't necessarily put out its
rated voltage.
