There is some kind of metal in the microwave. Maybe you have a gold edge around your plate or a metal twist tie. You can not put metal in the microwave (one metal spoon or fork will be okay.)
http://www.fsis.usda.gov/FactSheets/Microwave_Ovens_and_Food_Safety/index.asp#16Arcing (pronounced "AR-king") is sparks inside the microwave oven caused when microwaves react to gold paint on dishes, twist ties and other metallic materials. Some foods such as raw carrots and hot dogs can cause arcing while being microwaved. In hot dogs, this can be due to the uneven mixing of salts and additives. In carrots, it can be due to the minerals in the soil in which they were grown. Whatever the cause, turn off the oven immediately to end the sparks. Prolonged arcing can damage the oven and/or the utensil. If caught at once, arcing should not damage the oven. Remove the offending utensil or food from the oven and either substitute a microwave-safe utensil or cook the food by other methods.
If metal is left unexposed in a microwave oven, the metal will deflect the microwaves and cause sparks. However, if it is submerged in water, the microwaves dissipate and are absorbed by the liquid. In turn, the water is heated.
They get warm.(If you turn the oven on.)

Of course you can. But it would not be a good idea to turn it on.
If you place it inside and turn the oven on, I presume that the card will be damaged.

All microwave ovens have turn table. The heating in microwave takes place due to radiations and for getting uniform heating turn table is necessary. The fan helps in uniform distribution of heat which means the oven with fan for air convection will give better results.
Microwave ovens should not be used if the door will not close tightly. Most microwave ovens will not turn on without the door locking. The door has shielding in the glass to keep stray microwaves within the oven and not going into the room or the person operating the oven.
Never use oven cleaner in a microwave. Prevent the problem by leaving the door open after cooking. Clean the microwave by putting water in a cup and turn it on for 2 or 3 minutes. Wipe with a paper towel. The steam will remove stains and food after wiping.
Yep. It is called an inverter to convert 12 volts to 110 volts AC. Get one that will supply the amp needed for the microwave.
