Polarity of induced emf is such that end P acquires higher potential and end Q acquires lower potential so that positive charges flow from P to Q/electrons flow from Q to P. Induced current flows in the direction shown in figure.

Magnetic flux leaving a surface is positive and Magnetic flux entering a surface is negative.This is by convention that outward area vector is taken as positive.

In case of opposite of this ie when zero of Vernier scale is to the left of zero of main scale,zero error is -ve and zero correction is +ve. Important :-Here we will have to imagine the scale as there is no scale on the left of zero of main scale.

We are talking about magnetic flux linked with the coil .......therby decreasing the magnetic flux linked with the coil.......

Rare explanation of why Area is considered as vector in some situations.

What a simple explanation. Excellent. Thank you very much.

Important Value of S is so chosen that when Current I flows through combination,current Ig flows through galvanometer and current I-Ig flows through shunt resistance S. Full video link th-cam.com/video/XIAazelvA-A/w-d-xo.html

Important Value of S is so chosen that when current I flows through combination,current Ig flows through galvanometer and I-Ig flows through Shunt resistance S.

Impotant 1.Resistance of galvanometer is equal to resistance of its coil. 2.Normal to the plane of the coil means normal to area or in the direction of area vector.

Happy Diwali

Happy Diwali 🪔🪔🪔🎇 mam 🙏🥰🥰😊

Right hand palm rule - If fingers of Right hand point in the direction of magnetic field,thumb points in the direction of current then the direction in which palm points ,is the direction of force on the conductor.

Thankyou mam ❤❤❤❤❤❤🎉🎉🎉thankyou very❤🎉much

Om shanti mam❤❤

Mam ap kya Cp grater than Cv ka explain ker sakte hi 😢😢😢😢Cp>Cv

😮

Thank you mam😊😊

Very well explained.

Madam Sneh Lata is sharing her vast experience of teaching in a very simple manner. Excellent way of teaching. Thanks to her.

Derivation and diagram are as per NCERT Text book with the difference that.....here current flowing is denoted by i and in the book it is denoted by I

1.Direction of magnetic field B is given by right hand rule-curl the fingers of your right hand in such a way that thumb points in the direction of current,then fingers curl in the direction of magnetic field shown in the diagram(anticlockwise here) 2.Explanation of graph-As one moves from centre of wire to its surface,current enclosed by emperian loop increases from 0 to maximum( i ).So magnetic field inside the wire varies both with current enclosed and distance.Combined effect of the two gives B directly proportional to r. Beyond the surface of wire current enclosed by emperian loop becomes Constant ie i So magnetic field outside the wire varies with distance only which gives B inversely proportional to r.

Very easy to understand.

Technically complex subject of physics, i.e. electromagnetism has been explained in a very simple manner. Thank you Sneh Lata madam.

What a simplicity!

Thank u mam. It helps me lot . 🎉

Tutorials by Mrs Sneh Lata madam are extremely simple to understand. Excellent .

Clarifications 1.Magnetic field B at a point on the circular path is along the tangent drawn to the circular path at that point. 2.Law is proved for circular path but it is TRUE for any closed path irrespective of shape and size of closed path. 3.Gauss's law and Ampere's Circuital Law are more easy,convenient and appealing when there is symmetry(spherical symmetry or Cylindrical symmetry.)

Your english is very good mam ji

Very nice.

Additions 1.Conductors a and b will attract one another with a force = 2×10 to the power -7N/m 2.We conclude that parallel currents attract. This is opposite to that in electrostatics where we say that like charges repel.
