Understanding Magnetic Fields
- What is a rectangular magnet? A rectangular magnet is a permanent magnet with a defined length, width, and thickness, commonly used in scientific and industrial applications.
- Where is the magnetic field strongest on a bar magnet? The magnetic field is strongest at the poles of the magnet, where lines of force converge or diverge.
- How can you plot a magnetic field? Use iron filings or a plotting compass to visualize the magnetic field lines emanating from the magnet's poles.
- What happens when a bar magnet is cut in half? Each half becomes a new bar magnet with its own north and south poles.
- How do like and unlike poles behave? Like poles repel each other, while unlike poles attract.
