Electric & Magnetic Fields
Fun Facts
- Iron filings become magnetized, and their poles align with the lines of the magnetic fields.
- All magnets have two poles, a north pole where the magnetic field lines diverge and a south pole where these lines converge.
- Like poles of two magnets repel each other and opposite poles attract each other.
Why Do We Need To Know About Magnetic Poles
Learning about magnetic poles helps us understand how tools like compasses help people find their way. This is because the needle in a compass acts like a tiny magnet that lines up with Earth’s magnetic field. This is very important for jobs in mapping and sailing.
This knowledge is not only useful for navigation but also helps in many other areas like building planes, creating new materials, and making speakers work. For example, knowing about magnetic poles helps invent things like fast-moving planes without needing engines in the same way cars do, or making speakers that can produce sound. This shows how magnetic poles are important in a lot of different jobs.
