In this video we will cover:
1.A closed loop is held stationary in the magnetic field between the north and south poles of two permanent magnets held fixed. Can we hope to generate current in the loop by using very strong magnets?
2.A rectangular loop and a circular loop are moving out of a uniform magnetic field region to a field-free region with a constant velocity v. In which loop do you expect the induced emf to be constant during the passage out of the field region? The field is normal to the loops.
3.A small piece of metal wire is dragged across the gap between the pole pieces of a magnet in 0.5 s. The magnetic flux between the pole pieces is known to be 8*10-4 Wb. Estimate the emf induced in the wire.
4.Use Lenz’s law to determine the direction of induced current in the situations described by Fig: (a) A wire of irregular shape turning into a circular shape (b) A circular loop being deformed into a narrow straight wire.
5.A solenoid of length 50cm with 20 turns per cm and area of cross-section 40cm2 completely surrounds another co-axial solenoid of the same length, area of cross section 25cm2 with 25 turns per cm. Calculate the mutual inductance of the system.
6.Two coils have mutual inductance of 1.5 H. If the current in the primary circuit is raised to 5A in 1 millisecond after closing the circuit, what is the emf induced in the secondary?

I was feeling so low because my concepts were not clear, but ma'am with your videos my concepts are getting crystal clear. We are truly blessed to have such a wonderful teacher like you.❤️ Thank you so much Roshni Ma'am.🙏🏻❤️

[amysky]

2024 board's students give attendance here 😂😂

[ssubhashini]

57:45 ma'am, the answer should be anti clockwise as the induced magnetic field is outwards (as you have also written) .. Kindly clarify ma'am ☺️

Aap log bohot mehnat karke yeh animation ke sath videos banate hai appreciated!!!🤗

[ayushamansharma]

57:45
Since the the direction is upwards the direction of current will be anticlockwise.

[meharartstudio]

57:50 Dear ma'am the answer should be anticlockwise of the current bcz acc to ryt hand thumb rule the thumb would point towards the outward direction of magnetic flux represented by a dot so the fingers would curl in anticlockwise direction so that's why induced current direction must be anticlockwise ma'am pls check it once!!!

[simpleandusefulideas]

Complete biomolecules because you are an expert chemistry.

Hey 2023 Board candidate, Mark your attendance here. ⬇

[shubh-youtube]

My parents are thinking of me qualifying JEE and I am trying to get 70-80% marks in board. Feeling so low, I cannot share it to anyone so writing it here... Even thought to quit... but I am the only child who is studious...

[shreyasganeshhegde]

In the ocean of fear towards exam, you, and your fantastic videos, works as a lifeboat. Dhanyavaad mam, Bhagwan aapko sada prasanna rakhe.

[jackyff]

57:39 Mam in problem 3 it should be anti clockwise because induced emf should or will oppose change in flux, and flux is in down ward direction so induced current should be upward

[jahu]

Amazing lecture ma'am ❤️
Words alone can't repay all the efforts and hard works you invested to bring out the best I feel grateful for having a teacher like you. ❤️

[gurl]

These visualization makes remembrance easy 💕 Thank-you ♥️

[nourinroja]

Your teaching style is very different from others... You are unique ❣️❣️ After attending your lecture my concept are getting crystal clear...❤️

[AnnuYadav-thvh]

Aap itne acche se sabhi subjects kaise padha lete ho mam 🤗🤗. Concept hua crystal clear 👍👍

[harshcarvalho]

57:39 problem 3, direction of induced current should be anitclockwise

[aarishnaved]

You teach so good in short time and the work of animator is really appreciable ❤️

[awiralchhetri]

All isc students good luck for today's exam!❤️
