In this practical the flux density of a magnet will be found by measuring the force experienced by a current carrying conductor placed in the field using a digital balance. From the definition of flux density the force experienced by a current carrying conductor in a perpendicular field is given by:F= BILWhere B = Flux densityI = CurrentL = Length of conductor in the fieldWARNING Depending on the diameter and length...
