The line of "the magnet inside makes it difficult for the magnet outside" made me understand the entire concept. Much appreciated!!

[suhaimatunio]

you're a great teacher! my physics teacher explains less than a fraction of how well you do

[DoItLive]

love it. short sweet and to the point. just what I needed!

Excuse me, I'm confused. Why don't we use right hand grip rule here?

[ranggaeuy]

My teacher taught me this rule, and he used his right hand instead. This video is actually wrong.

Apart from the rule in this video, just look at the first example. Yes, to oppose the change by the magnet (magnetic field goes to the left), the current must be in the direction so that it will create magnetic field that goes to the right (he explained this well). However, if the current direction is like that, then it will create magnetic field that goes to the left, thus violating Lenz's Law.

If you do not believe me, try to use the usual right hand rule (fingers = magnet, thumb = current). To make the magnetic field inside the coil goes to the right, the current must be downward. (just ike giving thumbs down).

It might be confusing though if you use this rule with right hand as it's kinda the opposite (fingers = current, thumb = magnet). I prefer to just use the usual right hand rule.

Omg thank you so much, I was frustrated over this unit for my physics exam TOMORROW, and this video just happened to show up in my sub box. Once again, thanks :D

[hubercats]

Very intuitive presentation covering Lenz’s Law. Thank you!

[thesaxman]

depends whether you use right hand or left hand grip rule, its the same as the first example except poles are reversed and magnet is moving away

The first explanation I am understanding here on YouTube.

[AliDinkles]

Nicely presented, but Fleming's left-hand rule: Thumb (Thrust), First finger (Field) and seCond finger (Conventional current (opposite to actual)). Apparently, a different left-hand rule is operating.

The writing of the north and south on the actual coil was the game changer for me.

I've been trying to understand this for half an hour and I just couldn't make sense of it. I have an exam tomorrow and I am so greatful to have stumbled upon this video! The way you explained it made sense to me almost immediately!

[rayoflight]

Awesome video. Thank you for taking the time to explain a difficult concept in a simple way.

[adamwalkeraw]

You're talking about electron flow not conventional current when literally every exam will be talking about conventional current.... Not helpful bro. If ur gonna do that u need to put the Poles on the current or people will be confused

[chookers]

After watching every lens law videos, this is the only one 😭😭 TQ❤

[Mr]

Hello, (excuse my question but) Are you sure that the direction of the induced current is correct? It seems to me that the (for all 4 examples) current should be in the opposite direction? 

[motordemic]

Jeez! Man i love you! That analogy that it opposes the magnet made my learning and understand 100 better!

[jeffpeng]

Make sure you switch the direction if you are using right hand rule.

[naturalscene]

This is the best explanation I’ve seen

[Carmenckm]

I understood now after watching ye previous videos. Thanks so much!
