Study Notes
Magnetism Basics
- The end of a compass needle that points towards north is called the north-seeking pole.
Magnetic Interactions
- When like poles of magnets are brought near each other, they repel each other.
Magnetic Field Visualization
- When iron filings are sprinkled around a bar magnet and the board is tapped gently, the iron filings align with the magnetic field lines, revealing the magnetic field pattern.
Magnetic Field
- The region surrounding a magnet, in which the force of the magnet can be detected, is called the magnetic field.
Compass Needle and Bar Magnet
- A compass needle is a small magnet that orients itself in the magnetic field of a bar magnet, with the north-seeking pole of the compass needle aligning with the south pole of the bar magnet.
