Answer:
Due to orbiting of hydrogen nucleus, the magnetic field produced at the centre is equal to 3.2π×10⁻²⁷T.
Explanation:
A hydrogen nucleus has one proton. The charge on one proton is e= 1.6×10⁻¹⁹C. The charge is moving in circle, so the magnetic field produces equal to magnetic field in a loop by a circular current.
Magnetic field produced at the centre of the circle:
where, N is the number of turns,
and r is radius of circle and I is current.
We know that
Here, t = 1sec and q = 1.6×10⁻¹⁹C
So, current,
And. the number of turns, N=1
Given the radius of the circle, r = 1m
Substitute the value of I, N and r in equation (1);
Therefore, the magnetic field produced at the centre of the circle is equal to 3.2π×10⁻²⁷T.
