What did he see? A system that is still generating its own electricity without an external energy supply!
Thinking that Mystery Moon's ability is an enchantment type, the answer is almost ready to come out. She has given a new characteristic to the metal frame, using magic to provide a source of energy. ｜Chinese｜. .
"How did you do it?" Roland exclaimed.
"You said that electricity and magnetism are interrelated and are an inseparable whole. I can't help but think that since my ability can make an object magnetic, can it also make it generate lightning? You said that creating lightning requires changes in magnetic force, I tried to attach the repeatedly changing magnetic force to the copper wire, and it turned out to be like this..." Miyue replied cautiously, her eyes full of anticipation.
So it turns out... The prince thought, the current does generate a magnetic field, but the magnetic field does not generate a current unconditionally. The latter must act on the closed coil, and the magnetic flux changes at the same time. Whether it is changing the magnetic area or changing the magnetic force, it is necessary to external energy to achieve.
Mystery Moon's new ability replaced this part, allowing the magnetic force to change without external interference. If it was put in the past, Roland would definitely think that this was a perpetual motion model, but now he understands that the witch's ability cannot be used Common sense to measure the magnetism of an enchantment does not necessarily come from the magnetic pole, just as black fire is not fire.
These are the effects of magic.
The only thing he was curious about was that Mystery Moon had never noticed the magnetic change of the enchanted object before
When Roland asked this question, she first nodded, but then shook her head again, "During the mutual aid association, I also thought about letting the magnetism of objects change at will, and reducing the magnetism when not in use, so as not to give other sisters a chance. Cause trouble, but it doesn't seem to work, the magnetism of the object always maintains a fixed size, I thought this idea was impossible, and I didn't try it again."
Sure enough, Roland tilted his head and asked Nightingale, "Her form of magic..."
"It's condensed," Nightingale emerged from the mist and smiled, "It's like a surging blue water wave."
Mystery Moon's voice suddenly became excited, "Am I really?"
"Yes, your abilities have evolved," Roland affirmed. "Without long-term unremitting practice, it is impossible to grasp the key to promotion so quickly. You have performed very well. From today, you are the sixth in the Witch League. A witch with evolutionary abilities."
"Congratulations," Nightingale smiled and walked over to pat her on the head.
"Then can I do more for His Royal Highness now?" Miyue's eyes sparkled.
"Well, there are too many to count," Roland raised the corners of his mouth, "As I said before, your potential is limitless. But... take a good rest first, your dark circles are almost as big as your fists. .Wait until the afternoon and let me test your abilities."
"Yeah!" She nodded vigorously.
After Miyue left the office, Nightingale immediately closed the door and came over. She didn't go back to the table or the floor-to-ceiling window as usual. Instead, she came close to Roland, excitedly pressed his shoulders, bent down, and her pale blond hair fell on her cheeks, making him feel a little itchy. . Looking at Shui Yingying's eyes and soft red lips, Roland's heartbeat suddenly increased several times.
Eh? what's going on! Does she want to be here with herself... But it's still broad daylight.
"Tell me the method." Nightingale's words made the prince stunned for a moment.
"what way?"
"You don't need to understand the "Theoretical Fundamentals of Natural Science" to be able to evolve," she said excitedly, "With Mystery Moon's exam results, it is impossible to understand the content of this book, but you still let her evolve I have a new ability! What should I do? Do I need to practice with a small toy too?"
Uh, is it for evolution? It's really a pity, isn't it? It made people take a deep breath. Roland cleared his throat and gathered his mind, "I'm afraid it's very difficult to rely on your ability to understand. breakthrough."
"why?"
"According to Agatha, this requires witnessing phenomena related to ability in reality before it may lead to evolution, and your fog is so incredible, I don't know its specific principles, let alone guide you to understand it. Now," Roland explained, "If you want to condense magic, I am afraid there is only one way to go in the end, that is to master all knowledge of nature and physics, and advanced mathematics is also a skill that must be familiar."
Nightingale's expression immediately collapsed, and she weakly walked to the reclining chair and leaned against the back of the chair softly, as if her body had been hollowed out.
After lunch, Roland spent half a day conducting a comprehensive test on Mystery Moon's new abilities.
He named this ability indeterminate magnetism. Like the previous magnetism, it can be attached to any object and follow the magic power injected during enchanting to produce periodic changes, but for insulators, there is almost no current effect.
In addition, her magic power is also the lowest among the evolutionary witches. She can only light up the two magic stones on the Divine Will, which is half less than Maisie. And the enchantment type ability has a very high requirement for magic power. The larger the upper limit of the change of magnetic force and the longer the duration, the more amazing the magic power required. After a series of actual measurements, he found that the new ability of Mystery Moon was relatively stable as a battery. To drive a large motor and reach the power of an active steam engine, it is far from enough to use the DC motor assembled when the water was first electrolyzed into a motor. The test turned out to be pretty bad. Mystery Moon consumes all the magic power of the enchanted motor rotor and can only maintain the operation time for half a day, which almost negates its practical value as a source of power.
However, Roland did not disclose this to Mystery Moon, but encouraged her to continue practicing her new abilities and not to fall behind in her studies. For her, evolution was not easy, and any bad news might bring her down.
Fortunately, ability evolution is not a one-shot deal. As long as Mystery Moon can make another breakthrough through systematic learning, there is still a chance to make up for the lack of magic power.
In addition, Roland also thought of the method that Agatha said that multiple people work together to create luminous stones. If there is a witch who can control or transfer magic power, it can also bypass the limitation of Mystery Moon's own lack of strength.
In the evening, he found Tilly Wimbledon.
"Auxiliary witch of the magic control type?" After listening to the prince's narration, she pondered for a moment, "No one in Sleeping Island has such an ability."
"Yes... Is that so?" Roland couldn't help but sighed, it seemed that Mystery Moon could only rely on her own efforts to improve.
But Tilly's next sentence changed his expression, "But I know where you can find such a witch.".
