Case 1: when the magnetic induction varies linearly with time, as in each segment of the sawtooth wave, the induced voltage is constant in alternating directions, thus varying as a square wave in sync with the input signal. WWW www Q1.1: why does a linear change in voltage create an induced steady volt output at the probe? Explain with the use of the proper equation. Q1.2: Observe that during the upward rise of the "driving waveform at the big coils the steady voltage of the probe is negative. During the downward part of the driver voltage the probe signal is positive. Explain this in a short paragraph. Can you recall the name of the rule that governs it? Case 2: a sinusoidally varying magnetic induction produces a sinusoidal voltage lagging by 90°. Q2.1: Since the laws of physics are the same for sawtooth and sinewave then the two observations of the Q1.1 and 21.2 should apply here. Write a paragraph reflecting on how this applies. Q2.2: Recall from your trigonometry how can you use that the "voltage lagging by 90°" can be used to prove the generic form of a trigonometric function f(x): f(x+90) = -f(x). Show your proof.
