What Is an Induction Burner?
An induction burner usually refers to a single portable burner that can be used anywhere you can find electricity. Purchasing an induction burner is a great way to decide if you like induction cooking. The 1800W units are readily available for less than $60 and are handy to have around. Having an extra burner to plug in is useful when you're maxing out your stove with lots of cooking, or you can also place it in the center of a dinner table, turn it on low, and keep a soup or stew warm throughout a meal.
What is an induction cooktop?
An induction cooktop is a glass-topped magnetic heat source for cooking. It can be a flat unit that fits smoothly into your counter, a freestanding stove or range or a slide-in. Anywhere you have either a gas or a standard electric unit can be fitted for induction. Induction cooktops have been available for home use since the early 1970s, and now make up about 10% of new stoves sold.
What Is the Difference Between Electric, Gas and Induction Cooktops?
Gas and electric stoves transfer heat to pots and pans, and the food inside gets hot.
What type of pans work with induction?
Pans that work on induction cooktops must be magnetic. As a rule of thumb, these types of pans work with induction: cast iron (including enameled cast iron pieces, like a Le Creuset Dutch oven), steel, magnetic stainless steel (that contain a layer of iron) and carbon steel. All you need to determine whether your pots and pans are compatible with an induction cooktop is a magnet. If it sticks, you're good to go. If not, your pans are probably aluminum and won’t work. Many nonstick pans have aluminum bottoms and don't work on induction.
What is an electric burner?
A standard electric burner is a coiled heating element that is either exposed or under a glass or ceramic top. It heats up when you turn it on, glowing red from the heat. Electric burners can get very hot, often hotter than a standard gas burner. The drawback to an electric burner is that it takes longer to heat up and cool down when you change the temperature. The heating up time isn’t as worrisome as the cool-down time: turning an electric burner from high to low doesn’t mean you are instantly on low. It takes time to get there because the burner retains so much heat, and you may over-cook or burn what you’re cooking.
Is an Induction Cooktop the Same Thing As a Glass Cooktop?
All induction cooktops are glass, but not all glass cooktops are induction. There are many smooth black glass standard electric cooktops out there. The way to tell which is you have is to turn a burner on. The electric burner will glow red and you’ll feel the heat emanating from it. The induction burner won’t get hot and the LED on the control panel will probably flash an alert.
What is induction cooking?
Induction is electromagnetic. Magnets excite metallic pans to create heat. Pans essentially become burners, eliminating heat transfer through the glass cooktop surface unlike regular electric cooking, thus making it more efficient and safer. Induction cooking is available in a single "burner" or heating zone, a cooktop with multiple heating zones, or a range.
Why do people use induction cooktops?
Boucher prefers cooking with induction because it's faster and more precise. Not only does it heat two to three times more quickly than gas, Boucher says, but "you can choose a specific temperature and it's more consistent." Cleaning up is also much faster and easier with induction because only the pan is heating. The smooth glass top stays cool so drips and splatters don't stick and burn. Because the unused surface stays cool and is smooth , the cooktop effectively becomes additional counter space for cooking utensils, cookbooks, and other items you might not safely be able to place on a hot surface.
What kind of cookware is compatible with induction?

What is the biggest challenge in induction cooking?
According to Boucher, "The biggest challenge is the need to try it." Well, that and the learning curve that comes with adjusting to any new way of cooking. While the speed of cooking is an advantage, the rhythm and pace of cooking is not the same with induction. A home cook may initially be befuddled with disappearing touchscreens, adjusting to the speed, and getting used to the fact that when pans are removed from the cooktop it turns off. While this is a disadvantage initially, many appliance companies provide loaners and the opportunity to "try before you buy" in a showroom kitchen.
Why is induction cooking better than gas?
Because induction is more powerful than gas or traditional electric ranges, it is quicker, more comfortable, and ultimately makes cooking easier. It allows for manufacturer innovations.

Why is a glass top stove cool?
The smooth glass top stays cool so drips and splatters don't stick and burn. Because the unused surface stays cool and is smooth, the cooktop effectively becomes additional counter space for cooking utensils, cookbooks, and other items you might not safely be able to place on a hot surface.
When did Cooltech first commercially available?
Cooltech Applications launched their first commercially available magnetic refrigeration system on 20 June 2016.
What happens when the magnetic field decreases in a refrigeration process?
In that part of the refrigeration process, a decrease in the strength of an externally applied magnetic field allows the magnetic domains of a magnetocaloric material to become disoriented from the magnetic field by the agitating action of the thermal energy ( phonons) present in the material.
How does an adiabatic demagnetization refrigerator work?
The basic operating principle of an adiabatic demagnetization refrigerator (ADR) is the use of a strong magnetic field to control the entropy of a sample of material , often called the "refrigerant". Magnetic field constrains the orientation of magnetic dipoles in the refrigerant. The stronger the magnetic field, the more aligned the dipoles are, corresponding to lower entropy and heat capacity because the material has (effectively) lost some of its internal degrees of freedom. If the refrigerant is kept at a constant temperature through thermal contact with a heat sink (usually liquid helium) while the magnetic field is switched on, the refrigerant must lose some energy because it is equilibrated with the heat sink. When the magnetic field is subsequently switched off, the heat capacity of the refrigerant rises again because the degrees of freedom associated with orientation of the dipoles are once again liberated, pulling their share of equipartitioned energy from the motion of the molecules, thereby lowering the overall temperature of a system with decreased energy. Since the system is now insulated when the magnetic field is switched off, the process is adiabatic, i.e., the system can no longer exchange energy with its surroundings (the heat sink), and its temperature decreases below its initial value, that of the heat sink.
What is magnetic refrigeration?
Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as well as the ranges used in common refrigerators.
What was the original refrigerant?
The original proposed refrigerant was a paramagnetic salt, such as cerium magnesium nitrate. The active magnetic dipoles in this case are those of the electron shells of the paramagnetic atoms.
When was the first magnetic refrigerator invented?
Debye (1926) and W. Giauque (1927). The first working magnetic refrigerators were constructed by several groups beginning in 1933 . Magnetic refrigeration was the first method developed for cooling below about 0.3K (a temperature attainable by pumping on 3. He vapors).
