55867 Experimental Set-Up has been designed specifically to study the Faraday Effect and hence to determine the Verdets Constant for a given substance.

The set up is complete in all respect and requires no other apparatus. Practical experience on this set up carries great educative value for Science and Engineering Students.

OBJECT

To Calibrate the electromagnet and determine the verdets constant of substances like Glysrene, Potassium Chloride, and Potassium iodide solutions.

FEATURES

The Complete Experimental Set-up consists of following items. :
01 ELECTROMAGNET : The electromagnet have the most widely used ‘U’ shaped soft iron yoke. The soft iron is of a special quality, structurally uniform, well machined and finished to meet the rigid standards also has tapard the pole pieces with bhor of ½" along the axis of coils.
