Experiment methodics
One has to measure magnet pointer’s angle of deviation due to various values of coil current. The dependence of deviation angle tangence versus magnetic field of coil is plotted. Horizontal conponetnt of terrestrial magnetic field is determined. |
Device construction
The device is implemented as coil of 0.21 m diameter with 6 turns of isolated wire. Magnet pointer is fixed in the center of coil at horizontal site. The case has a scale marked up to measure rotation angle. The pointer is put inside the case. The case is fixed so that the "0-1800" markup line lies in a plane of coil. To avoid mistakes in measuring the magnetic field, the case is made of non-magnetic materials. DC power supply and digital multimeter are required. To carry out the experiments you will need: power supply 220/24 V 6 A (regulated) |
