WebThe induced current I 2 gives a magnetic flux that opposes the change in magnetic flux I B produced by the wire current I 1. Hence, the direction of the induced current I 2 can be determined by using the right hand screw rule. In figure 1, if the current I 1 is increasing the magnetic field through the coil is increasing in the –Z direction. Web5 nov. 2024 · Faraday’s law states that the EMF induced by a change in magnetic flux depends on the change in flux Δ, time Δt, and number of turns of coils. Faraday’s … cup of raspberries in grams
