Abstract
A metal-coated fibre was injected with an electric current into its jacket for magnetic field detection using a Lorentzian force. AC and DC field detection sensitivities of 25rad/Gs and 15-7rad/Gs and linearity over four decades have been obtained with a 100 mm sensing fibre. This configuration can also be extended to multiplexed DC magnetic sensors.
