Circular Coil Apparatus (For Magnetic Field)

red wood stand brass terminals superior A coil with 94 turns of 1 mm

dia. Copper wire is mounted on a plastic base, and surrounds a plastic sheet on which iron

fillings can be placed. Used to observe static magnetic fields generated by a constant flowing

current. For demonstration on static magnetic fields. This coil can be used with classical iron

fillings for magnetic field pattern study and also with a compass to see the magnetic effect of

current similar to a tangent galvanometer.
