Current Magnetic effect Appa

This instrument can be used to demonstrate the magnetic field line in straight line current magnetic field, ring current magnetic field and electrified solenoid magnetic field. Supply voltage 4V-6V

Features

• It features a compass at the center of a coil of wire.
  
• The base has terminals with different numbered values (20, 10, 8, 6, 4, 2, 1) and is marked "DC6V," which likely indicates the voltage and different current settings or coil turns.
  
• The tangent galvanometer is used to demonstrate the relationship between electric current and magnetism.
