Adjustable Magnet

Item no.: XMG910010 Description Consisting of a steel frame with lockable, adjustable jaws which can accept 50 × 20mm ferrite slab magnets or neodymium button magnets. The field strength can be changed by adjusting the distance. Use with the B.I.L Coil (S100-170) to determine the flux density in the gap. The unit is supplied complete with 2 ferrite

Magnetic field of paired coils in a Helmholtz arrangement with Cobra4

Item no.: P2430362 Principle The spatial distribution of the field strength between a pair of coils in the Helmholtz arrangement is measured. The spacing at which a uniform magnetic field is produced is investigated and the superposition of the two individual fields to form the combined field of the pair of coils is demonstrated. Tasks

Magnetic and Electromagnetic Experiments

Item no.: F18 Introduction In1820, an electromagnetic theory was initiated by Oersted. Here the physical experiment relative to magnetic field induced by a current-carry wire was proposed. During 1820~1827, the theoretic model was further quantified by Ampere’s. In 1831, the so called Faraday’s law amounted the current induced along the closed loop while a time
