Magnetic field (induction) due current in infinite straight conductor (wire)
$$B = \frac{\mu\cdot \mu0\cdot I}{2\cdot \pi\cdot r}$$
B - magnetic induction
μ - relative magnetic permeability
μ0 - magnetic constant
I - current intensity
r - distance to conductor
μ - relative magnetic permeability
μ0 - magnetic constant
I - current intensity
r - distance to conductor
Find
It is known that:
=
