circularconductor

03-017 A circular conductorThe conductor is used to demonstrate and to experiment with the generation of a magnetic field by a current flowing in the conductor. By spreading iron fillings and placing magnetic needles one can demonstrate:1. The shape and the direction of the lines of magnetic field force round the conductor2. The shape and the direction of the lines of magnetic field force in a circular conductor with a current3. The dependence of magnetic field intensity in a circular conductor on the current intensity4. The logic of the right-handed screw (corkscrew) and the clock. While demonstrating these one may use an overhead projector for rear projection. Dimensions: 150 x 80 x 335 mm, conductor- copper wire 2 Cu - 150 mmWeight: 0,13 kG 03-018 A solenoidIt is used to demonstrate magnetic field as generated by a current flowing in a solenoid or to experiment with the subject. When using a DC power source, iron fillings and magnetic needles one may demonstrate:1. the magnetic field of the solenoid as a superposition of fields of circular conductors that are connected in series2. the homogenous field inside the solenoid3. the analogy between the solenoid magnetic field and the field of a bar magnet4. the logic of the right-handed screw (corkscrew) and the right-hand principle5. the dependence of the solenoid magnetic field intensity on the intensity of the current flowing in the solenoid. The transparent plate helps to demonstrate the above phenomena on a screen with the help of an overhead projector. Dimensions: 47 x 120 x 235 mm, conductor: copper wire 2 mmWeight: 0,13 kG
