Electric motors are nothing more than is a mechanical device that switches electric energy into mechanical energy by passing an electric current through a wire loop contained within a magnetic field. A solenoid, universally used in all motor types from power door locks to starters and is simply a round coil of insulated wire used to create a magnetic field in the presence of this current.
Because a solenoid is a specially designed electromagnet in which a coil of wire is wrapped around a specifically shaped core made of iron or steel, it is an integral component in motors of all sizes.
Here's are the basics of how a solenoid operates: when electrical current goes through the loop of wire, a magnetic field accumulates around it. A steel or iron path for this force to flow into will greatly increase the intensity of the magnetic field. Considering that magnetic energy attempts to take a specific path, flowing from the center of a coil, out one end, down the sides and then reversing that path. If a steel or iron core, called a solenoid, is shaped to fit this path, it will then direct the flow of magnetism through it.
If gaps are left in the core design, the magnetic flux will flow around the path until it is stopped by the resulting breach. The solenoid armature will fill the gap; thus, when the current flows through the coil, it will attract this moveable plunger into the gap, thus completing the electrical circuit. This plunger can subsequently be attached to various mechanical parts, which, in turn, will cause them to move in a defined direction. Depending on which end of the armature is connected to the solenoid, a pushing or pulling motion results. Very often, springs are employed to keep the plunger position set to open.
Electric motors are based on the basic rule of thumb that all current-carrying wire within a magnetic field contains a degree of mechanical force. The bigger the motor and the larger the electromagnetic field, the more power is exerted. A string of check valves and solenoid switches can harness this power in a controlled manner, depending on the direction and force required. The real power behind any motor is controlled by different factors including the amount of turns in the coil, the quantity of current flowing through it, the length end to end of the coil and the magnetic superiority of the steel or iron used in manufacturing the parts that move.
To conclude, by applying the basic tenets of electromagnetic knowledge and by adapting the parts to withstand the relevant pressure, all motors, regardless of their size operate on this same scientific principle.
It could just be that when you speak to a person and tell that you do all your cooking on an induction stove you will be asked the question what an induction stove is. A lot of people may have heard of it but probably have never cooked on one and may even not understand the principle behind it. For more details go to.com We can put cooking stoves in to 2 major categories namely gas and electric. There used to be 3 but coal/wood these days are only use for barbecues or some other type of outdoor cooking but for day to day cooking we use either gas or electricity.
With a halogen or coil element stove they produce the heat that gets transferred to the pot, pan, cooker etc. etc. and then to the contents of those, with induction it the other way around. When you're cooking on an induction stove the pot or pan is the one generating the heat. When you hear this for the first time it might be a bit confusing to you but it is not that hard to understand. Ones you understand the principle behind induction cooking and you get your first experience with this type of stove you will probably never want to cook on anything else again.
An electric stove with a coil or halogen works in such a way that once you turn the stove on the element (the coil or halogen) will start to heat up. It does not matter if there is a pot or pan on that element or not it will heat up either way. That heat is then, like we said before, transferred to the pot or pan and then to the food. When you take the pot or pan of the element it will remain hot until you turn it off, for more details visit to www.apples-recipes.com then it will slowly start to cool but this will take some time. With induction cooking the element will start to produce a high frequency electromagnetic field which passes right through the pot or pan. The pot or pan must be made out of magnetic material. This electric (magnetic) current that circulates is what generates the heat. This is the big difference between induction cooking and the other two types of electric cooking.
Now that the pot or pan is heating up that same heat is transferred to the food or liquid that is inside it. The moment you take the pot or pan from the stove (element) the magnetic field that was circulating is broken and stopped and immediately the generation of heat stops as well. With a coil or halogen element you have to turn the element of to stop the heat generation, with induction cooking there is no heat as long as there is no electromagnetic field circulation. For more details go The only heat you will feel when you take the pot or pan from the stove is the heat that was transferred from the pot or pan into the surface of the stove, for more details visit to www.chef-123.com not the element it self because that never produced the heat.
There is one thing that you have to keep in mind when you would like to start cooking on an induction stove. You can only use steel or iron pots because the material needs to be magnetic in nature.
But if you are used to cooking electric then you will find that once you cook with induction you will probably not be going back to that halogen or coil element.
