Задача 30789.

The intensity of a uniform electric field inside a flat air condenser with round plates of radius 10 cm increases linearly with time: E = at, where a = 9 * 10 ^ 10 V / (m * s). What is the magnetic field induction modulus inside the capacitor at a distance of r = 5 cm from its axis?

A detailed solution with a brief record of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
If you have questions about the solution, write. I will try to help.
