Why do magnets attract or repel? What is the difference between magnetic field and magnetic force? Explain why a soft-iron core increases the strength of an electromagnet. Why the ferromagnetic materials can be magnetized easily? How do electric and magnetic forces relate to ...
Why do neutrinos change into other kinds while traveling? How does light behave as a particle? Why do magnets attract or repel? Why is gravity so heavy? Why are neutrons needed to trigger fission in a nuclear reactor? What is the Universe - space or matter?
Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also push other magnets away. So how come you feel only the pull of gravity? In 1915, Alber...
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. Experiment Extension Tip...
Electromagnetism is the superhero force that makes motors spin. Just think for a second about how two magnets facing each other with the same polarity tend to repel, and likewise how magnets pull together when opposite polarities are facing (opposites attract). So imagine if ...
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...
As soon as the objects are "let go" in any of these cases, they will move. The Slinky will pop up, the arrow will fly to the target or the particles will attract or repel. Why Conservative Forces Matter Conservative forces allow humans to store energy that can later be put to useful...
Why do magnets repel each other? Why is motion a keyword for magnetism? How do fundamental forces relate? Which is stronger: magnetism or gravity? Why are diamagnetic substances repelled by magnetic fields? How does Newton's universal law of gravitation work?
32K There are various types of magnetic materials and magnets can both attract and repel each other. Learn more about the properties of magnetism and how the Earth's magnetic field is used to navigate by animals, including humans. Related to this QuestionWhy...
Why do like charges and poles repel, unlike charges and poles attract? If energy creates gravity, why is gravity not energy? Why are there probably no permanently aligned magnetic domains in Earth's core? Explain why the distance from mirror to object is the radius...
