Consists of a round spiral coil passing through a transparent base plate to carry current.
· Magnetic field shape around a solenoid coil can be demonstrated; Suitable for use on an overhead projector
· Use a plotting compass or sprinkle iron filings on the base plate so that the magnetic field formed around the solenoid coil can be easily observed and studied.
· Size (approx.): 140 x 96 x 54mm
