Quiz: Do you Know how Induction Cooktops Work?
by Staff
What do you know about induction cooking? Is induction cooking better than conventional cooking? Take our thought-inducing quiz to learn about induction cooking.

How does an induction cooktop compare to conventional cooktops?

  • heats faster and is easier to clean
  • easier to clean but cooks at a lower temperature
  • heats more slowly but reaches a higher temperature

What is heated during conventional cooking?

  • the food only, not the cookware
  • the entire surface of the pot or cookware
  • the surface of the pot or cookware that touches the heat source

How precisely can temperature be controlled through induction cooking?

  • very accurate
  • not at all accurate
  • depends on the brand

The term electromagnetism refers to the relationship between __________.

  • protons and electrons
  • electricity and magnetism
  • magnetism and electrons

How does electromagnetism occur?

  • A circuit of alternating current causes a current to flow in another circuit.
  • A direct current such as a battery causes a current to flow in another circuit.
  • A magnetic field generates electricity and sparks an alternating current.

What scientific principles are bound by Faraday's Law?

  • All electric currents have gravitational forces that generate magnetic fields.
  • All electric currents have magnetic fields, but alternating currents have magnetic fields that fluctuate and induce other currents to flow.
  • All electric currents have induction properties, but magnetic fields generate more currents to flow.

How does induction cooking work?

  • Coils carrying alternating current affect the surrounding magnetic field and induce current in the cookware.
  • Electromagnetic current heats the cookware by causing the coils beneath to reach high temperatures.
  • Ferromagnetic cookware generates an electric current in the cooktop and heats the food.

How many volts are induced in the cookware surface during induction?

  • 1 volt
  • 5 volts
  • 10 volts

What are eddy currents?

  • swirling currents
  • small electric currents
  • incomplete circuits

Why is iron the material of choice for induction cookware?

  • It is an excellent conductor.
  • It converts the flow of the current into heat.
  • It allows currents to flow easily through it while generating high heat.

Are aluminum pots a good choice for induction cooking?

  • only if they have copper bottoms
  • only if they have iron bottoms
  • never

How can you tell if your pot is suitable for induction cooking?

  • If a magnet sticks to the bottom of the pot, it'll probably be good for induction.
  • If your pot is ovenproof, it'll probably be good for induction.
  • The bottom of the pot will say "Induction Certified."

How much faster than a conventional cooktop does an induction cooktop heat up?

  • 10 to 20 percent faster
  • 25 to 50 percent faster
  • 50 to 75 percent faster

How much radiation does induction cooking emit?

  • less than an airport scanner
  • more than an airport scanner
  • about the same as a small x-ray

What is the price comparison between induction cooktops and gas ones?

  • Induction cooktops can be three times the price of gas ones.
  • They cost around the same.
  • Gas cooktops are more expensive.

Why might the installation of an induction cooktop be unsuitable above an oven?

  • It would sit too low.
  • It would be inaccessible by people in wheelchairs.
  • It might have a fan underneath.

How much heat radiates from an induction cooktop surface?

  • none
  • minimal heat
  • the same as a conventional stovetop

What were induction cooktops originally designed for?

  • nuclear testing
  • restaurants and industrial use
  • chemistry labs

What voltage and amperage do you need for induction cooking?

  • 110 to 120 volts and more than 50 amperes
  • 208 to 240 volts and up to 50 amperes
  • 208 to 240 volts and up to 100 amperes

What features do most induction cooktop appliances have?

  • safety lock, pan size adapter and warmer
  • safety lock, overflow detecter and auto shut-off
  • safety lock, turbo mode and auto shut-off
