Tangent Galvanometer-Economical

Simple And Economical Tangent Galvanometer Is Specially Designed To Demonstrate That A Current Carrying Coil Produces A Magnetic Field Perpendicular To The Direction Of The Current. On Placing A Magnetic Compass On Transparent Platform, Students Can Visualize That Any Change In Electrical Input In The Coil Produces Change In Teh Magnetic Field Also.
