You can ask a question like, “Why are magnets strong?” that’s a good way to figure out whether magnets lose energy. To give you a brief summary, we’ll cover:
1) The basic idea of a magnet is to rotate or rotate the opposite direction in order to create an even magnetic field. (In order to do this, some sort of rotating motion is needed.)
2) In many cases, a strong negative charge tends to attract a strong positive charge. This happens when the opposite ends of the charges bump into or meet.
3) Sometimes the opposite ends of a charge come together in a “charge circle” that gives it an even magnetic field.
4) When a magnet has attracted more positively charged charges than negatively charged ones, it usually changes direction. This can be seen in the figure to the side. For example, it is easy to see that the “down” side is more positively charged than the “up” side. It is also easy to see that if a positive charge is attracted to a negative charge, there is an even higher attraction than if there had been negative charges.
5) If you turn a magnet on its side, or magnetize it, the same thing happens. If a magnetic field is strong, it can act like a negative charge of a field. Also, when two charges move, the opposite ends attract each other as well. (This also works with magnetic fields that are aligned with polar coordinates for the same reason.)
6) A negative charge does not have to attract positive charges, even when the difference is larger. A positively charged positive charge will not attract a negatively charged negative charge.
7) The same thing can happen even if the charge change is different than the force that causes it. Some fields have much fewer strong negative charges than others, and this is why you can make some magnets stronger than others without changing their shape or size.
8) In addition to making the field of a magnet stronger, there is no law saying that one side of a magnet always attracts, or that one side always repels. (As the illustration shows, the positive side of the magnetic field will repel the opposite side.)
9) If the opposite pole of a magnet is closer to a higher energy field, and the direction of the field tends to move toward that side, the opposite end of the magnet may be attracted less strongly to that higher energy field than the positive side. Sometimes a magnet may have
