Evaluation of SMF Exposure Field Levels and Gradients Obtainable Using the 2d Magnetic Arrays

Abstract

Abstract. Two-dimensional magnetic arrays have been proven useful as exposure setups for biomedical experiments with static magnetic fields. Different static magnetic field levels as well as vertical field gradients can be attained from these exposure setups by means of varying the geometrical parameters of an array and the type of magnetic material employed. Evaluation of obtainable field and gradient values has been conducted by varying one by one parameter. Several relevant parameters were chosen to represent the effects of input parameter changes on the magnetic flux density above the array. Calculations were conducted using the exact analytical expression.
