In this photo, a magnetic stove top is depicted. Pictured is the magnetic stove top with its multiple circular burners of many different sizes across the surface. This is the type of stove my family uses at our cabin.
Summary: Most people use stove tops in their houses to cook meals. These days there are hundreds of stove options when looking for new kitchen appliances. However, there is one stove top that is becoming more and more popular in households each day, and that is the magnetic stove top. There are various reasons people are choosing these types of stove tops over other …show more content…
Once the AC power supply is turned on, the current running through the coil produces a magnetic field in its surroundings, specifically above it. As long as the current is flowing, a magnetic field is produced. Once the power is shut off, the current ceases and the magnetic field disappears. The current that is produced is how much charge passes in an amount of time, through the coil. This current is an alternating current (or AC) because it has oscillating charges. Furthermore, the magnetic field is created above and below the ceramic top plate of the stove. A magnetic field occupies the space around a magnet as in the case of the magnetic stove top. Within magnetic stove tops there are magnets. The magnets are above the electronic supply and have the coil attached to them. When the magnetic field is created, it is created above the …show more content…
A major component of magnetic stove tops is magnetic thermal induction. In charging by induction, the objects do not actually touch, but instead the process charges a neutral object to another charged object, and the newly charged object will have a charge opposite in sign to the original charge. In relation to the magnetic stove tops, the induction coil carrying the AC current is induced alongside a magnet, and a magnetic field is produced. The coil does not actually make contact with the stove top. This is charging by induction and it occurs underneath the stove top.
Also, there is the concept of charging by conduction, or involving the physical contact of a charged object to a neutral object that goes on. With conduction, it leaves the neutral object with the same charge as the first charge. This involves the transfer of energy between objects in thermal contact via the agitation of molecules, while the object is stationary. This occurs between the pots and the stove top because conduction is the process whereby heat is transferred directly through a material (being the stove top to the pot). (cite physics book) Charging by conduction happens above the stove top and needs to involve a conductive utensil, or specific pots and pans that allow for this process to occur. This is one of the problems with magnetic
