Our Products
Our product range contains a wide range of Square Section Solenoids, Demagnetising Solenoid and Open Wound Solenoid
It facilitates learning of induction and its dependence on total turns, turns per unit length, current flowing and cross sectional area of the coil.
A set of 4 square section solenoids, two having a cross sectional area of 4000 mm2 and length of winding 295 mm. Turns per unit length ratio is kept 1:2 by close wounding, one by 380 turns anc' other is open wound by half i.e. 190 turns. The other two coi have a cross sectional area of 2000mm. The number of turns usei in each case is same as for larger coils, solenoids 325 mm (overa length), large coil 325 x 64 x 74 mm, small coils 325 x 45 x 55 mm.
Solenoid is wound with 250 turns of heavy gauge enameled copper wire on insulating bobbin 80 x 19 mm (length x I. D.) to take 2 A for a period upto 30 min will be able to accept rectangular magnets of cross section upto 15 x 6 mm, fitted with 4 mm sockets.
This simple solenoid is to explain the electromagnetic field outside and inside a solenoid. A heavy gauge copper wire, wound and mounted on wooden base and provided with 4mm sockf terminals. Suitable for field demonstration using iron fillings o using a small compass needle. Overall dimensions: 330 x 260 x 87mm. Solenoid current carrying capacity is 10 Amp.
