Question

identifying tools to test for magnetic fields
which would you sprinkle around the electromagnet that you produced in the laboratory activity to see its magnet field lines?
which would you use to determine the direction of the field lines around a magnet?
wh determine if a magnet was moving in close proximity to the circuit?
saw dust
sifted flour
iron shavings

Explanation:

Iron shavings are magnetic materials. When sprinkled around an electromagnet, they align themselves along the magnetic field lines due to the magnetic force exerted by the electromagnet. Saw dust and sifted flour are non - magnetic materials and will not show the pattern of magnetic field lines.

Answer:

iron shavings
