Magnetic field of the solenoid can be represented by the voltage

Click For Summary
SUMMARY

The magnetic field of a solenoid can be represented by the voltage induced in a search coil, as established by the relationship between magnetic field strength (B) and current (I). The formula for calculating the magnetic field inside a current-carrying coil is B = (μ₀I)/(2πr). By substituting the current with Ohm's Law, I = V/R, one can express the magnetic field in terms of voltage and resistance. Understanding this relationship is crucial for applications involving solenoids and electromagnetic fields.

According to which law the magnetic field of the solenoid can be represented by the voltage induced in the search coil ? :rolleyes: :biggrin:

Here's a formula that's use to find the field inside a current-carrying coil (should work for this too):

[tex]B=\frac{\mu_{0}I}{2\pi{r}}[/tex]

And as you probably know:

[tex]I=\frac{V}{R}[/tex]

Now just substitute (you do need to know the resistance inside the loop, though). I think this is what you are looking for.
