1. A 100-turn, 2.0-cm-diameter coil is at rest in a horizontal plane. A uniform magnetic field 60 degrees away from vertical increases from 0.50 T to 1.50 T in 0.60 s.
2. EMF = N*d(phi)/dt
phi = flux = ABcos(theta)
3. dB/dt = 1/0.6
EMF = 1000*(1/0.6)*pi*r2*0.5 = 0.262 V
Is that correct? Should the sign be negative?
