![]() In the clockwise direction over here that too when you do your right hand rule right over here your fingers would coil around that way. In the counter clockwise, or sorry if you're going The current in that direction would also when you take your right hand and you were to put it along here. The current right over here would produce a magnetic field that's going downward. Induce a magnetic field that would decrease the flux. We take our right hand point our thumb in theĭirection of the current point our thumb in theĭirection of the current and we see if we do that So, just by deductive reasoning we know that this is going to be the scenario and let's see if we thinkĪbout what happens here. We would not want theĬurrent that's been induced to induce a magneticįield that goes in the same direction as our increase in flux. That's a pretty goodĪrgument for why we would not expect the counter clockwise scenario. And so that's a pretty good argument for why you would not. The current is going to increase even more which is going to make theįlux increase even more and which makes theĬurrent increase even more and you would have this never ending cycle where the current keeps increasing, the flux keeps increasingĪppearing out of nowhere which would violate the law Well, what would that do? If the flux increases even more then the current is going to increase. In fact, at these points these vectors would increase even more. So, notice it would be additive to the existing magnetic field. It, if we were to sample it points right on the surface the magnetic field that would be induced would look something like this and I'm just doing itĪt some sample points. Magnetic field being induced that would wrap around like that. Something like that thumb in the direction of theĬurrent right over here we see that it shows the So, when I do that with my right hand, so my right hand looks So, my thumb in theĭirection of the current and then my hands are going to loop or I should say myįingers are going to loop in the direction of the magnetic field. I can take my right hand point my thumb in theĭirection of the current. So, if it's going in theĬounter clockwise direction remember we use the right hand rule. Type of magnetic field that this orange current Will induce a magnetic field above and beyond a magnetįield that's already there. We know that a current flowing through a wire actually on it's own So, which of these two do you think the current will actually go with? Well, let's think a little bit about it. ![]() The clockwise direction or it could go in theĬounter clockwise direction. And so an interesting question is what direction is that currentĪctually going to go in? We have two options. And we know from Faraday's law that when you have a change in your flux that that's going to induceĪ current in the loop. The flux of the magneticįield has gone up. The wire at every point the magnetic field has We have increased the flux at these points on the surface defined by So, both of these pictures right over here they actually show the same scenario where we have increased the flux. If I were to actually change the flux going through the surface. So, if we just had this scenario nothing too special going on but it becomes interesting Or that is contoured by the wire that the magneticįield looks constant. You can see at least on the surface that is defined Vectors that represent the magnetic field and ![]() Let's say it's a wire and it's stationary and it's sitting in a magnetic field. So, right over here depicted a square loop of a conductor.
