 SOLENOID (HELIX), IRON CORE

 

For studying magnetic induction properties produced by electric current and the effect of an iron core, etc.
Consists of a plastic spool with windings of enamelled copper wire having brass binding posts on square end supports. Includes a soft iron core rod of diameter 18cm and instructions.

Cat. No.

3171-00


 SOLENOID (HELIX), AIR CORE

 

To provide external magnetic field where required and to change the rate of magnetic flux passing through a coil.
Consists of a plastic spool with windings of insulated copper. End plates have brass binding posts. Capacity 10 amperes when used intermittently and 5 amperes when used continuously.

Cat. No.

3172-00


 PRIMARY AND SECONDARY COIL SET

 

For studying electromagnetic induction, ferromagnetism and principles of a transformer.
Consists of two coils wound with enamelled copper wire over heavy plastic spools fitting one within the other. The inner primary coil has 1250 turns of heavy wire and the outer, acting as secondary coil with 250 turns of fine wires. Square supports of thick insulating material are used as vertical or horizontal mount. Both coils are equipped with binding posts and a soft iron core for induction studies.

Cat. No.
