Abstract
A penlight constructed of materials including metal components having very low magnetic susceptibilities is described. The battery powering the penlight lamp is a lithium battery also constructed of materials having low magnetic susceptibilities. The penlight is particularly useful in the vicinity of the strong magnetic field of an MRI scanner.
