Specifica�ons for Brand name or equal to Pasco Purchase: E/M
Apparatus (SE-9629):
A large, helium-filled electron tube is mounted between a pair of Helmholtz coils. The tube contains an electron gun, which generates a focused beam of electrons. A measured current is applied to the Helmholtz coils so that the magnitude of the magnetic field within the electron tube can be calculated. A measured accelerating potential (V) is then applied to the electron gun. The magnetic field (B) deflects the electron beam in a circular path with a radius (r) that is measured using the illuminated mm scale. Individual specifications of the E/M apparatus are found in the table below and it must be compatible with Pasco Devices. Link to product page can be found below:

QTY- 11
Rota�onal Iner�a Accessories (ME-3240):
The Rotational Inertia Accessory can be added to the PASCO Rotary Motion Sensor to study the oscillations of a pendulum, the rotational inertia of a disk, a steel ring and a metal rod, as well as the conservation of momentum during a rotational collision. The Clamp-On Super Pulley allows students to apply a torque by hanging a mass over the pulley. Individual specs of each material are below and they all must be compatible with the Pasco Rotary Motion Sensor. Link to product page can be found below:
