magnet and coil
A magneto provides pulses of electrical power to the spark plugs in some petrol-powered internal combustion engines where batteries are not available, most commonly those in 2-stroke and 4-stroke engines used in small motorcycles, lawnmowers and chainsaws, as well as in most small aircraft and some racing automobiles, serving a similar function to the coil-type ignition system found in automobiles. In aircraft, typically each cylinder has two spark plugs, each driven from a separate magneto. This arrangement provides redundancy in the event of a failure of one of the magnetos, and two sparks burn more efficiently than one.
Magnetos combine the functions of a dynamo, contact breaker points and coil into one unit. The engine rotates a coil of wire between the poles of a permanent magnet to provide a basic source of electrical energy (In some variants the permanent magnet is rotated and the coil remains stationary). On each revolution, a cam opens the contact breaker one or more times, interrupting the current, causing the voltage in the secondary winding of the coil to reach a very high value, enough to arc across the electrodes of the spark plug. Because no battery or other source of energy is required, the magneto is a rugged, reliable and self-contained solution to providing ignition of the fuel. In some modern magneto designs, an electronic switch replaces the contact breaker.

Bought Camera From Argos?
Nicole
Lost my camera last week, went to argos today to purchase a new one, got a hitachi brand 12mp set me back £80, basically bought it in store tried to turn it on outside in the foodcourt, battery wasnt charged (so even if i had of asked to see the quality in store this would not of been possible) Went home, charged the battery turned it on, awful quality of photos flash makes them ghost like, and macro setting is awful.. I am comparing this camera to the cheaper 12mp Alba i purchased the previous month which was outstanding but unfortunatly they stopped selling it therefore I had to chose a different model...
So my question to you is the 30 day guarantee does not apply to cameras, but im sure if A. i couldnt test the camera instore and B. the quality was not as described for a camera which apparently was priced at over £200 prior to the sale.. That it should be high quality? and not this pixelated probably 5mp crap that I have recieved..
How should I go about returning this item?
I did put it to the highest setting, due to my photography background I know about settings etc. I did go into argos the very next day and they could see what I meant and happily exchanged my camera to a different model
Answer
Ok if you are going to return it I recommend you do it asap, the 30 day money back guarantee DOES NOT apply to cameras, or any other high-value electrical items. If you look at the receipt it does state this underneath the product description (*Exempt from 30 day money back guarantee) and thus Argos are not obliged to give you a full refund unless the camera is faulty and after being sent for testing and is irreparable.
Additionally, no retailer is allowed to sell an item stating that it is less than the specification given on the ticket/in the catalogue. The Trading Standards act (1970-specifically) denounces this practice as illegal and retailers can be sued or shut down.
If you state that you're unhappy with the quality, Argos are not legally obliged to refund or exchange it for you, however if the camera is clean and (looks) unused, and if it's within a couple of days from the purchase date they may exchange it.
If you state that the camera is faulty, they will send it for repair. There's no way they will refund you without sending it away first.
Argos do not test camera's in-store as they don't have staff trained or the facilities specifically to do so. Also keeping charged batteries in a camera is classed as a biohazard and a fire risk, in the same respect that they do not keep lawnmowers already full of petrol.
There are a couple of points I have that might help you without having to go through the hassle of taking it back to the store.
1) Are you definately sure you've set the DPI/Resolution on the camera to 12mpx? As with most camera's, they're not automatically set to their highest quality settings and it has to be done manually. Check your instruction manual for details on how to do this.
2) If you bought the camera close to the new catalogue launch date, all stores drop the price in order to clear particular lines. If Argos do no longer sell your camera, it's classed as RO stock. Ask at the tills to see if any other store in your local area has one still in stock. You will have to travel to pick it up as Argos do not transfer stock between stores.
Hope this helps.
