Magnetic Field At The Centre Of Rotating Sphere || Irodov 3.247 Magnetism Problem

3.247. A non-conducting sphere of radius \(R = 50\text{ mm}\) charged uniformly with surface density \(\sigma = 10.0\text{ }\mu\text{C/m}^2\) rotates with an angular velocity \(\omega = 70\text{ rad/s}\) about the axis passing through its centre. Find the magnetic induction at the centre of the sphere. #irodovsolutions #irodov #jeeadvance #iitjeepreparation #physics #physicsstudents
