Given that the area immersed in the gap is changing as the coil enters the gap, what is the correct expression of Faraday's Law for this situation? That is, find the induced voltage as a function of the velocity of the glider, \( v \), the flux density inside the magnetic gap, \( B \), and other quantities you can measure from the video. Hint: This is an
Given that the area immersed in the gap is changing as the coil enters the gap, what is the correct expression of Faraday's Law for this situation? That is, find the induced voltage as a function of the velocity of the glider, v, the flux density inside the magnetic gap, B, and other quantities you can measure from the video. Hint: This is an example of a motional emf, which is something that we covered in the lecture. You should already know the equation for this.
