Undervisningsmateriale

Supplier: CORNELSEN EXPERIMENTA

Instrument for comparing charge amounts. When charging, a hand is repelled from the jumper it is hung in. Mounted on a plate.

Supplier: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.

Supplier: 3B Scientific

Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off and power supplies for direct connection to photo gate or a Geiger-Müller counter.

Supplier: CORNELSEN EXPERIMENTA

With the equipment, centrifugal forces that arise during a body's rotation around a specific axis can be measured and examined. The device consists of a plane with a path for a cart. On the underside there is a vertical shaft that is mounted in a bearing. The plane is made to rotate with a laboratory motor connected with a drive belt to the bearing. The experimental trolley is placed on the track and prevented from leaving the track by two bent steel wires. A wire is connected to the trolley that runs over a pulley and on to a dynamometer.
