*Lenz's Law explains how a changing magnetic field induces an electromotive force (EMF).*
*Statement*
The direction of an induced current in a circuit is always such that it opposes the causes that produced it.

*What is Lenz's Law?*

Lenz's Law states that the induced EMF in a circuit opposes the change in magnetic flux that produces it. This means that the induced EMF tries to resist or counteract the change in magnetic flux.

*Direction of Induced EMF*

To determine the direction of the induced EMF, we use the right-hand rule:

1. Point your thumb in the direction of the changing magnetic flux (increasing or decreasing).
2. Your fingers will curl in the direction of the induced EMF.

*Key Points*

- The induced EMF opposes the change in magnetic flux.
- The direction of the induced EMF is determined by the right-hand rule.
- Lenz's Law helps us understand the relationship between magnetic fields and electric currents.

*Example*

Imagine a coil of wire with a magnet moving towards it. As the magnet approaches, the magnetic flux through the coil increases. Lenz's Law states that the induced EMF will oppose this increase in flux. Using the right-hand rule, we can determine the direction of the induced EMF.

I hope this explanation helps you understand Lenz's Law and the direction of induced EMF!

Thank you sir this video is very helpful for me

Sir hassan, aapko seekhna chahiye in se itna acha samjhate hain

[sarakhan]

Sir the direction of current is clockwise

[AliRaza-redi]

sir apne ulta kr dia closckwise r anticlockwise

Sir according to book first one is clockwise??

[naseemabid]

Sir ye be to ho saka he ke magnet ka jese hamne north samja he wo south ho or conductor ka south north ho hame kese pta chala ke magnet ka wo north he.
Wese opposite poles me attraction ya reppaltion kuo hote he

[pclyzfb]

You are the best teacher 😊😊I am proud of you 😊May Allah bless you

[mussratparveen]

Sir jab ham magnet ko solenoid ke qareeb latey hain to north pole or jab dooor lei jatai hain to south pole q develop hota ha? 😮😂

[amnakhalid]

sir clockwise direction kesy o skti ha..jab south pole attract ota ha?

[meerhakim]

When the magnet is near ...the current is anticlockwise and far the magnet is clockwise ❤

[muhammadishaq]

Nice video..but direction of current are not drawn correctly

[princes]

Sir agr hm activity ka serf diagram banaye or explain na kare toh num mel jaye ge board paper main

[funtimelol]

Very well explanation 👏.
Keep it up 👍.

[naseemabid]

North pole or south pole dono change kuo hote hein age peche karne se

[RashidaAbbas]

First current is in CLOCKWISE direction and secondly the current is in ANTICLOCKWISE direction

[naseemabid]

Fingers se anticlockwise or clockwise ka kese pta chala

[Hafeezkhan.]

Sir es North Pole k formation ka waja kia hian

[mooeezmoeez]

Wow sir one of the best Vedio I have ever seen on physics lecture
