@AnyaRaii In 2023, I was in class 12th , I was enrolled in Allen , kota. My jee mains crl was 5906 (210 marks) and jee advanced crl was 10,305 (123 marks). I was interested in becoming a researcher in physics. But , I did not get Engineering Physics branch in any of the IITs and this branch is not available in NITs. So, I joined unacademy kota in drop year as most of my allen teachers had joined unacademy kota (currently, they left unacademy) . But, after course completion, they did not provide a satisfactory revision programme. So, I did all the revision part myself. PYQs were a boon. For physics revision, I used revision checklist and then shifted to advanced illustration and booster checklist for jee advanced. In drop year, my jee mains crl was 2400 (260 marks in 29 Jan shift 2) and jee advanced crl was 3115 (191 marks, phy:69, maths:44, chem: 78) . So, I got engineering physics at IIT Roorkee.
10:09 field ka direction is outward by right hand thumb rule. But using dl × r we get -k^. Also in vector form it is -ive because the direction of field is from that point i.e origin to dl.
Sir my question is, I have only done 75% syllabus of physics . Is it sufficient for jee main. But I follow Block method very strictly suggested by you in CAPS.
Sir i think there's a correction in Bp(axis), which we have derived by horizontal component method, at 58:10, in that denominator me 'R', nahi aayega, or else formula by both method will not give same result. Thank you very much sir for this type of amazing checklist...

Sir I Could not understand the formula for magnetic field due to a revolving charge at axis at point P in time instant 57:50. Is there any mistake in that formula?? Because R is present in both numerator as well as in the denominator??
Consider a cross-section of the cylinder perpendicular to its axis. The cylindrical cavity is shown at a distance I from the axis 0 of the cylinder. We will calculate the magnetic induction at the point P inside the cavity. The cavity means absence of current which we consider as an equivalent opposite current of same current density in the cavity. Magnetic induction at point P inside cavity is given by subtracting the magnetic induction due to opposite current considered in cavity region from the total magnetic induction at P due to complete solid cylindrical wire. Expressions for the magnetic induction due to wire and that due to the opposite current in cavity is given.

Sir can you pls tell the answer of Magnetic Field inside a cavity of a cylindrical conductor.
Consider a cross-section of the cylinder perpendicular to its
axis. The cylindrical cavity is shown
at a distance I from the axis 0 of the cylinder. We will calculate
the magnetic induction at the point P inside the cavity. The
cavity means absence of current which we consider as an
equivalent opposite current of same current density in the
cavity. Magnetic induction at point P inside cavity is given
by subtracting the magnetic induction due to opposite current
considered in cavity region from the total magnetic induction
at P due to complete solid cylindrical wire.
Expressions for the magnetic induction due to wire and that
due to the opposite current in cavity is given.
