Ответ:

1.25*10^-6 Тл

Объяснение:

I=0.25 A a=0.04 м μо=4*π*10^-7 Гн/м μ=1 B=?

===

B=μo*μ*I/(2*π*a)=4*π*10^-7*0.25/(2*π*0.04)=1.25*10^-6 Тл

Benjamin Franklin.

Benjamin Franklin (1706 - 1790) was an American printer, author, publisher, inventor and scientist. He was born in Boston, in January 17, 1706. His father was a maker of soap and candles.

In 1714 Ben was sent to a school that lasted the year round. There was no summer vacation.

The opening bell rang at 8 a.m. in winter and at 7 a.m. in summer.

Girls were not allowed to enter. All the teachers were men. The boys were whipped even for a mistake in their lessons.

The books were written in Latin. The pupils were to study Latin all morning and in afternoon they studied Latin again. Every boy had to learn everything by heart.

Franklin’s curiosity about natural phenomena was observed from his boyhood. In the winter of 1746 - 1747, he began his experiments with electricity. He did not know what electricity was, but he knew that it could pass through a metal wire. The result of this experiment was the lightning conductor. He invented many of terms such as battery, semiconductor, etc. Heat, light, sound magnetism interested him and hydrodynamics, chemistry, geology, physiology, psychology, oceanography as well.
