No. Stainless steel includes several families with different magnetic properties. Ferritic, martensitic and duplex stainless steels can be strongly attracted to a magnet.
The British Stainless Steel Association explains that magnetic response depends on the steel's internal structure. The Australian Stainless Steel Development Association confirms that common austenitic grades, such as 304 and 316, usually show little attraction in their annealed condition, while other families are strongly magnetic.
Manufacturing also matters. Cold working can change the structure of some austenitic steels and increase their attraction to a magnet. A magnetic response therefore does not, by itself, mean that an item is not stainless steel.
Stainless steel can be magnetic. Its grade and processing history affect how it responds to a magnet.

The association identifies ferritic, martensitic and duplex stainless steels as magnetic, contradicting the blanket claim.

Yes. Solar panels can use diffuse daylight when clouds block direct sunshine. Their output generally falls as less sunlight reaches the cells.
Yes. Synthetic aperture radar sends its own pulses and uses their echoes to form images. It can operate through clouds and without sunlight.
No. Watts measure power consumption, while lumens describe light output. A more efficient bulb can produce the same amount of light using fewer watts.
