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.

• 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 &quot;Induction Certified.&quot;

### 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
