Helmholtz coils are normally connected in series so the current passing through them is the same.
The power source for these coils is normally a constant current power supply where the current remains exactly constant even when the coils heat and the resistance rises.
Specifications:
- Coil Diameter:
- Inside: 115mm Outside: 163mm
- Average coil diameter:
- 150mm
- Number of turns:
- 400 per coil
- Maximum current:
- 1 amp
- Coil resistance:
- Cold: approx 20 ohms Hot: approx 25 ohms
- Power source:
- So that the heating of the coil does not change the current flowing, use preferably a constant current supply, adjustable from 0 to 1 amp. The maximum voltage required is about 26 volts.
- Physical:
- Weight: 0.84 kg. For the set of 2x coils and the scale.
