The first Philosopher's Stone was successfully made a day later and placed on Murphy's desk.
It was a crystal-like stone, glowing red, slightly smaller than Nicolas Flamel's. Severus Snape explained that this was because Murphy had obtained less primordial matter than Flamel had back then.
Tests showed that this Philosopher's Stone could steadily provide magic power at a rate of six hundred "Haber" per second.
"Haber" was a unit of magical power named after Haldan Haber.
One Haber was roughly equivalent to the magical power required for a Lumos bright enough to illuminate an ordinary classroom.
Even under maximum load, consuming eight hundred Haber of magic power per second would not reduce the Philosopher's Stone's total magical power.
That was already roughly equivalent to the normal magical output of four hundred ordinary wizards.
Thus, a Philosopher's Stone like this could easily power a magical radar.
And that was under continuous use. In reality, because the Philosopher's Stone's magical regeneration had the property that the less magic power it lost, the more efficiently it recovered, its maximum output could be even higher if it was used intermittently and given time to regenerate.
To put it simply, if the Philosopher's Stone consumed two thousand Haber of magical power, it might need two seconds to recover. But if it consumed only one thousand Haber, its recovery time would be less than one second.
No one knew the principle behind this effect, but based on it, maximizing the frequency of magical output and stoppage could potentially increase the total amount of magic power output.
Calculations showed that if high-frequency intermittent magical output was performed at one kilohertz, the Philosopher's Stone could output more than eight thousand Haber per second, and that was still far from its limit.
Using this Philosopher's Stone, Murphy created the
