AIR CORED SOLENOID 700 TURNS 5A COPPER WIRE
Air Cored Solenoid is formed on a strong moulded plastic bobbin and is used in several experiments. It can be mounted over the 'Magic Eye' tube for the Mass of Electron experiment, or used for making the Current Balance apparatus, or used for calibrating the Hall Effect apparatus or used for any time a magnetic field is required of known field strength.
It contains 700 turns of copper wire and can carry about 5 amps maximum current. Size is 150mm long and 37mm bore. The wire terminates to 4mm socket head terminals which point inwards so that the ends of the solenoid can sit flat on the table.
