Circular conductor radius of 5.2 cm with a current I1 = 13,4 A and straight wire carrying a current I2 = 22 A are in the same plane. The distance from the linear conductor to the center of a circular current of 8.3 cm. Find the magnetic induction in the center of a circular current if the conductors are in the air. What will be the induction at the same point, if the direction of the current in a straight conductor is reversed?

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
