WebMagnetic fields are relativistic electric fields (ie. the creation of an electric field due to space contraction from moving charges), but this was not known until Einstein's theory of relativity. Before relativity was discovered, magnetic fields were known to be generated by current (ie. moving charges) or changing electric fields. Comment Web1 dag geleden · Learn about magnets and their many uses. Magnetic forces When two magnets are close, they create pushing or pulling forces on one another. These forces …

The force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. Magnetism works over a distance. … explain dysphasia
Year 3 science: Forces and Magnets - eLearning App By …
Magnets exert forces and torques on each other due to the rules of electromagnetism. The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Both of these are modeled quite well as tiny loops of current called magnetic dipoles that produce their own magnetic field and are affected by external magnetic fields. The most element… Web8 nov. 2024 · pdf, 154.19 KB. pdf, 1.07 MB. This worksheet is designed for GCSE Physics students.
