Magnetic field in matter
WebCritical teaching ideas. Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets. At standards up to and including Level 3, it is appropriate to encourage students to observe and ...

Web17 aug. 2024 · Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic Anomaly, or SAA – allows these particles to dip closer to the surface than normal. Web15 jun. 2024 · Moreover, the magnetic fields are always associated with surface currents flowing in an orthogonal direction; these currents have a numerical value equal to ¯ H. The perpendicular electric fields are always associated with a surface charge ρs numerically equal to ¯ D ; the sign of σ is positive when ¯ D points away from the conductor. …
