To understand the physics behind a homopolar motor, first and foremost you have to understand that besides the electric current in a current-carrying wire there is also a magnetic current (which the contemporary science calls magnetic field). The two currents are inseparably bound to each other very similar to the water swirling current and the cavitation spiral current which an underwater propeller creates. The water swirling current corresponds to the electric current, whereas the cavitation spiral current corresponds to the magnetic current. Watch the cavitation spiral current in this short -
1 law cant create energy. ok but you can give energy to a ferromagnetic and magnetize it. then magnetize as many ferromagnetic material as you want, and not diminish the magnetic field of the 1st one you had. I dont understand how no loss and how that is not considered braking the 1st rule -
No, it cannot be arbitrary at all. (in this answer I will use the words “plus” and “minus” instead of “positive” and “negative”) “Plus” is the effect towards outside (expansion, blowing, explosion), “Minus” is the effect towards inside (contraction, suctioning, implosion). For example, the act of inhaling is plus, because our chest expands; the act of exhaling is minus, because it reduces in size. From the history of electromagnetism it is known that Benjamin Franklin (1705-1790) is the man who was the first to introduce the terms “positive” and “negative”, i.e. “plus/minus” in the field o

Let us consider some experiments. We place a stiff copper wire on a table. Parts of its length don’t touch the table. Above a wire section that does not touch the table we hold a strong cylindrical magnet with its plus-pole down (N-pole), so that the wire lies exactly under the middle of the magnet. Then we connect a new battery to the ends of the wire so that the plus-pole is closer to us and the minus-pole further away from us. At the moment of connection we will notice that the wire makes a strong deflection to the left and up. As soon as we turn the magnet over and repeat the same, the wir

The fundamental forces, like gravity, electric force and magnetism are explained via the mechanism of a screw, where a "Field Line" is interpreted as a turning screw and the direction of the linear force is obtained by the right hand rule. This simple screw mechanism was briefly alluded to by Maxwell in his famous four part paper, The Physical Lines of force. My work can be found at the link below: If you have any questions please feel free to ask them. Thank you

Hello, I have four questions. As it stands now, I don't have the necessary materials to test this myself, which is how I'd prefer to learn the answer. I still plan on doing this experiment for fun once I can acquire the necessary components. This deals with Lenz's Law. My goal is to maximize the time it takes for an object to fall through a tube. 1) Most folks demonstrate Lenz's Law by dropping a magnet down a copper pipe. From my understanding, the relative motion of the magnet, to the copper pipe, is responsible for creating Eddy currents, which, in turn, provide an opposing force on the m
