### HELMHOLZ COILS

#### ► STUDY OF MAGNETIC FILED OF TWO COILS

Exp- To study the magnetic field along the common axis (at different points o the axis ) of two coils when the distance between the coils is equal to, greater than and less than radii of the coils.

DIGITAL GAUSS METER WITH AXIAL PROBE
Works on the principle of Hall effect of semiconductors. Current carrying semiconductor when placed in a magnetic field of direction perpendicular to the current direction produces emf directly proportional to the intensity of the magnetic field. Supplied complete with Gauss probe.

Range        : 0.2K gauss & 2K gauss.
Resolution : 0.1 gauss at 0-2K gauss.
Power        : 230V ± 10%, 50Hz AC.

D.C. POWER SUPPLY:
Range                  : 0-16V, 0-5Amp.
Voltage                : Continuously variable and stabilized.
Display                 : Two separate displays (3 digit LED) are provided to monitor the output voltage and load current continuously.
Working Voltage : 230V AC, 50Hz.

COILS:
Material : Copper.
Quantity : One pair of equal radii and number of turns 100 or more.
