Description:

Demonstrate B around a permanent magnet (bar or cylindrical) using iron filings.
Notes: You can show B around a permanent bar magnet using iron filings sprinkled on a piece of cardboard or paper. This can also be demonstrated on an overhead projector using a container that has iron filings suspended in silicon oil.
Location:

LDL-D4: Container of iron filings
LDL-D4: Bar Magnets (1)


LDL-D4: Iron filings in container of silicon oil
LDL-D4: Cylindrical magnets (2)
