JEE Advanced Physics Syllabus can be referred by the IIT aspirants to get a detailed list of all topics that are important in cracking the entrance examination. JEE Advanced syllabus for Physics has been designed in such a way that it offers very practical and application-based learning to further make it easier for students to understand every concept or topic by correlating it with day-to-day experiences. In comparison to the other two subjects, the syllabus of JEE Advanced for physics is developed in such a way so as to test the deep understanding and application of concepts.

Q1.  A conducing ring of mass 2 kg and radius 0.5 m is placed on a smooth horizontal plane. The ring carries a current of i=4A. A horizontal magnetic field B=10 T is switched on at time t=0 as shown in Figure. The initial angular acceleration of the ring will be
Q2.A wire is bent in the form of a circular arc with a straight portion AB. Magnetic induction at O when current I flowing in the wire, is
•  μ_0/2r(π-θ+tan⁡θ)
•  (μ_0 I)/2πr(π+θ-tan⁡θ)
•  (μ_0 I)/2πr(π-θ+tan⁡θ)
•  (μ_0 I)/2πr(-tan⁡θ+π-θ)
Q3.  A consider a hypothetic spherical body. The body is cut into two parts about the diameter. One of hemispherical portion has mass distribution m whicle the other portion has identical charge distributionq. The body is rotated about the axis with constant speedω. Then, the ratio of magnetic moment to angular momentum is
•  q/2m
