Abstract
The utility model provides a magnetic field intensity measuring apparatus, which relates to detection quality control field of magnetic powder, especially to the field of magnetic field intensity measurement. A Hall element (6) of a teslameter (7) is fixed on a horizontal support rod (5) which is equipped with a pedestal (3) and a vertical support rod (4). The position of the Hall element (6) in a magnetic field is adjusted through scale intervals of the vertical support rod (4), a contraction gauge (10) and a contraction gauge (11), wherein a fixing bolt (8) is adjusted to enable the Hall element (6) to be perpendicular to the magnetic line direction of the magnetic field, magnetic lines vertically penetrate through the Hall element (6), and magnetic field intensity measuring data is reflected on a processor of the teslameter (7). The magnetic field intensity measuring apparatus can accurately locate a magnetic field measuring position, avoids the disadvantage that the Hall element is not stably held by hands, reduces damages of strong magnetism to operators, and can conveniently measure the position of the Hall element in a magnetic coil through the contraction gauges mounted on the pedestal.
