To map the magnetic field around a current-carrying solenoid, a student can use either iron filings or a small plotting compass. Which statement correctly describes what each method is able to show?
Both iron filings and a plotting compass can show both the field pattern and the direction of the field lines.
Iron filings can show only the field pattern, whereas a plotting compass can show both the field pattern and the direction of the field lines.
Iron filings can show both the field pattern and the direction of the field lines, whereas a plotting compass can show only the field pattern.
Iron filings can show only the direction of the field lines, whereas a plotting compass can show only the field pattern.
