There are two solenoids X and Y with lengths \(20\text{ cm}\) and \(40\text{ cm},\) respectively. If the current intensities flowing in X and Y are \(1\text{ A}\) and \(2\text{ A},\) respectively, what is the ratio of the intensities of the magnetic fields induced inside X and Y?
The number of turns of the two solenoids are the same.
