The video below shows an apparatus to demonstrate electromagnetic induction. Let's use this video to explore electromagnetic induction. Begin by watching the video. 1. Notice that the voltmeter moves in response to the coil entering or leaving the magnetic gap. 2. Let's apply Faraday's Law to this situation. Faraday's Law says that the induced voltage (or emf )in a loop of wire caused by a changing magnetic field is: 6 = Where I is the magnetic flux which is D = BA In this case, the flux density B is not changing. Instead, the changing flux is due to the motion of the coil as it enters or leaves the magnetic gap: do = BdA 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. BIU FEFE Of N= number of coils V= velocity R= length of coil b= breadth of coil x= magnetic field is into the page when rectangle coil is moving with velocity V out of the magnetic field. The breadth changes at the rate of Vm/s out of the field. The rate of change of area can be represented Flux-B*V*b m^2/s The rate of change of magnetics flux=N*B*V*b dtheata/dt= rate of change of flux=B*V*b dtheata/dt=N*B*V*b FarDAY'A LAW E=dtheata/dt When evaluating each equation I got E=N*B*b*V E= induced EMF N= number of coil b= breadth of coil V= Velocity of coilElectromagnetic Induction Interactive Next, watch the video below. This interactive video allows you to measure the speed of the glider and the omf generated by the coil passing through the magnetic gap. 0 0 0 0 TRIAL 3 Change 1.
