Demonstrate the good rule of thumb for designing a simple magnetic coil? Particularly, given a circular coil of radius ~1cm, determine the estimated magnitude of the magnetic field, in gauss per amp per turn (Note: 1g = 0.0001 T.)
i) 0.0001 G/(A-turn)
ii) 1 G/(A-turn)
iii) 0.01 G/(A-turn)
iv) 100 G/(A-turn)
