An electron moving in a circular orbit of radius r makes n rotations per second. The magnetic field produced at the centre has magnitude:
-
- Zero
-
μ0n²e r -
μ0ne 2r -
μ0ne 2πr
Correct Option: C
Radius of circular orbit = r
No. of rotations per second = n
i.e., T = 1/n
Magnetic field at its centre, Bc =?
As we know, current
| i = | = | = en | ||
| T | (l/n) |
= equivalent current Magnetic field at the centre of circular orbit,
