Einstein’s general relativity explains gravity as the result of spacetime curvature due to mass, contrasting with magnetism’s dual ability to attract and repel. This theory introduces the concept of gravity wells, central to understanding gravitational pull. Credit: SciTechDaily.com Why does gravity...
Why do magnets attract or repel? Why does a negative charge move from low to high potential? Define electrostatic. Why can't all materials become superconductors? Which atom in ClF is more negatively charged? Why do the oppositely charged plates of a capacitor attract each other?
If bar magnets are allowed to attract and stick long sides together, what happened to the total strength of the magnetic field and why? Why do we weigh more at the poles? Explain how magnetic flux can be zero when the magnetic field is not zero. Why do we prefer steel or alnico ...
The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. ...
We can represent this as magnetism because even the magnets attract each other when there are two opposite poles meet. Since there is enough force to drag the thin water flow, the water stream shows little movement when a negatively charged object comes in close contact. ...
They come in pinks, reds, oranges, purples, blues, whites, and yellows. One of the best parts about this flower is that not only do they attract bees, but they also actively repel deer. 22. Larkspur (Delphiniumspp.) An excellent flower for bringing in bees is the larkspur, or as it...
Electric Safety (Do not need to write) Never handle when wet or near water Never run wires under carpet Never overload circuits Repair worn out wires Put nothing in electric sockets that does not belong Never go by fallen wires or power lines In lightning storms get down to the ground by...
Luckily, many atoms, including hydrogen and anti-hydrogen, have a “magnetic moment”. While they are electrically neutral and unresponsive to electric fields, they do act like little bar magnets and we can use that to keep them suspended. Even so...
Answer and Explanation:1 If we compare both Gauss's laws from electrostatic and magnetostatic we can see that there is a very important difference between the sources of the... Learn more about this topic: Gauss' Law | Definition, Equation & Examples ...
Why do we have free electrons in metal and not in insulators? What makes them be an insulator/semiconductor/metal? Why are the magnetic fields of superconducting magnets often stronger than those of conventional magnets? Explain the space c...
