When used in conjunction with the Helmholtz pair of coils D and S (1000644 and 1000611) and the Perrin tube D and S (1000650 and 1000616) two orthogonal magnetic fields can thus be generated at right angles to the tube axis to demonstrate the basic principles of a cathode ray oscilloscope.\u003cbr\u003e\u003cbr\u003eProduct Information: ..\u003cbr\u003eThe air filled coil is made of lacquered copper wire on a plastic bobbin with a lip for securing to the fork of the tube holder D (1008507).
