The value of the magnetic induction at the center due to the current in the ring can be found using Ampere's Law. Ampere's Law states that the line integral of the magnetic field around a closed loop is equal to the product of the current enclosed by the loop and the permeability of free space.
In this case, the closed loop is the circle formed by the ring, and the current enclosed by the loop is the current passing through the ring.
The current passing through the ring can be found using Ohm's Law: I = V/R, where V is the voltage of the battery and R is the resistance of the ring.
The magnetic field at the center of the ring can then be found using Ampere's Law: B = (μ₀I)/r, where μ₀ is the permeability of free space, I is the current passing through the ring, and r is the radius of the ring.
Since the current passing through the ring is the same for all points on the circumference, the magnetic field at the center of the ring is also the same for all points on the circumference.
Therefore, the value of the magnetic induction at the center due to the current in the ring is proportional to 2πq/360, where q is the angle subtended by the arc AB at the center.
