yes we can produce electricity without magnetism by using semiconductor for example photo diode is used in solar cells.
A cockroach does not produce electricity. A cockroach is an insect that can live even with its head cut off.
a power plant is a factory that produces lots of electricity. It might even produce electricity to your whole state
Even without electricity i can write a good paragraph by using candles as an alternative use..
The world has gone a sea change after the invention of electricity. Today, without electricity even for few minutes, life become gloomy. The monetary loss in the financial sector without electricity is unimaginable. All activity will be in a stand still without the noble hand of electricity.
They would work without electricity if they're battery operated. Like the example here http://www.startechoutlet.com/
A small amount of electricity can be generated without DC excitation due to the phenomenon of electromagnetic induction. When a conductor moves through a magnetic field, or when the magnetic field around a stationary conductor changes, an electromotive force (EMF) is induced. This can happen in various systems, such as in generators or even through residual magnetism in the system, allowing for the generation of small amounts of voltage without the need for external DC excitation.
Residual magnetism is the magnetism that remains in a material even after an external magnetic field is removed. This phenomenon is commonly observed in magnetic materials such as iron and steel after they have been magnetized. Residual magnetism allows these materials to retain some magnetization and can be useful in applications such as magnetic memory storage devices.
A buildup of charged particles on a material can produce static electricity. This static electricity can result in sparks, crackling noises, or even small shocks when the charged material comes into contact with another object.
No because if you think about it, they couldn't see where they are going and they couldn't see any x-rays. So the answer is no. Even when the electricity goes out (mainly caused by thunderstorms) they have a generator to continue having electricity.
Yes, magnetism happens even under water.
Attraction between objects does not exclusively indicate magnetism because other forces, like gravity or static electricity, can also cause objects to attract. To prove magnetism, additional tests are needed, such as demonstrating repulsion between like poles of a magnet or showing that the attraction follows the inverse square law as magnetic force does.
In order for one to produce electricity at home, they would need either solar panels on their roof or get a electical turbine to catch the wind and turn it into power. There are many products avilable on the market for people who want to do this and can even get government credit for making these modifications to their home.
