In a laboratory experiment, a rectangular loop was pulled horizontally at different speeds ν through a uniform magnetic field B produced by a set of Helmholtz coils. The induced electromotive force (EMF) 'ε' across the loop was measured using a computer-interfaced motion sensor and voltmeter. The following table lists the recorded values of speed, 'ν' (m/s) and induced voltage, 'ε' (V):

Determine the best-fit linear equation for the data. [Hint: Plot a graph of the induced voltage 'ε' versus speed 'ν'.]

• A. ε = 0.15v
• B. ε = 0.27v
• C. ε = 0.32v
• D. ε = 0.35v
