Reference: AQA
Plotting fₙ against 1/L, against √T and against 1/√μ to obtain straight-line relationships through the origin if the theory holds.
Plotting T² against mass m gives a gradient of 4π²/k, and plotting T² against length l gives a gradient of 4π²/g.
Repeating for several currents and plotting F against I, where the gradient is LB, so B = gradient / L.
