electric motors are an electomagnet spinning round, changing poles so that it can always repel magnets attached to the sides and therefore spin.
Innovative discoveries in electricity and magnetism, a new science in his day.

National Static Electricity Day is celebrated on January 9th each year. It is a day to raise awareness about the phenomena of static electricity and its effects.
i really don't know
You use electricity every time you use a light-bulb, a computer, an electric stove, a refrigerator, etc. You use magnetism (as well as electricity) every time you use an electric motor, or a loudspeaker. For example, the motor in electric toys, in a refrigerator, or in a hair drier.
Newton did not invent electricity. The very basics of electric charge had been discovered millennia before Newton's birth. The English physician William Gilbert advanced this somewhat looking at the relationship between 'electricity' and magnetism 43 years before Newton's birth. All this work was fundamentally with "Static Charge" rather than what we now generally know as electricity. Michael Faraday was the first to apply electricity and magnetism to a practical use through the invention of the electric motor, transformer, and other electrical devices we use every day. The first battery was developed by Alessandro Volta in 1800 some 73 years after Newton's death. For lots more info on the discovery of electricity see the Wikipedia link below.
Electricity was a big one. Also, the wheel was a pretty big deal back in the day, as was fire.
the worn out to every day
People use magnetism in various ways, such as in magnetic compasses for navigation, in MRI machines for medical imaging, in electric motors and generators for converting energy, and in data storage devices like hard drives and credit cards. Magnetism is also used in everyday objects like refrigerator magnets and headphones.
Maxwell described that electricity and magnetism cannot be separated. If you examine maxwell's equations you can see that a moving electric charge will produce an electric field. You can also see that a magnetic field that changes in time can produce an electric field. Maxwell also predicted that an electric and magnetic field can propagate infinitely together- this is called a wave (otherwise known as light, x-rays, microwaves, etc...).
The amount of coal used each day can vary widely based on factors such as the size of the power plant, its efficiency, and the electricity demand. On average, a coal-fired power plant might consume thousands of tons of coal per day to generate electricity.
