Helmholtz Coil

Material	Copper
Brand	Arco
Diameter	5 Inch
Country of Origin	Made in India

Helmholtz coil, 4Amp approx., is a device for producing a region of nearly uniform magnetic field.

It consists of two solenoid electromagnets on the same axis. The solenoids are made by moulded bobbins (diameter approx. 5" approx.) in circular shape and 4mm induction safety sockets are provided for high current rating.

A metallic clamp is also provided to hold the magnetic probe (magnetic field sensor, used to calculate the magnetic field across the solenoids).

Besides creating magnetic fields, Helmholtz coils are also used in scientific apparatus to cancel external magnetic fields, such as the Earth's magnetic field.
