Question

P2) Using Vemf derive the voltage Vo generated by the Faraday disk generator dt shown below. (Refer to your class notes to review how we derived the induced voltage using (u x B). dl) Vo 21 3

Answer 1

P b Voltage between Peints D an & S VI toetweet, peint P and n find VoB Now, rew Faradays law af Eectromagnetic nduction, hahen ever +hese is re lative wotion between cenductos and nagnetio field B, an ent is devela ped a nehese magni tude us enols acoase Canductor dinen toy dp dt P BA A is varying ttere, B ws Censtant and - B dA dt .V

Let, in time the disk Totate ay au oungle A-BD Area swap tn Avea &wap in 2 Tad e bad and obuiaus +his area swapped changin usith time pubing -B d be dt B dA at 17 DB do -Bb o V dt -7 $2 ve' sign is according to dery las
