A circular coil with a diameter of 25.0 cm and 158 turns rotates about a vertical axis with an angular speed of 1230 rpm . The only magnetic field in this system is that of the Earth. At the location of the coil, the horizontal component of the magnetic field is 3.81×10−5T, and the vertical component is 2.85×10−5T.
Find the maximum emf induced in the coil.
Answer in mV

Solutions

Expert Solution

E_max = ωNBA

Given angular speed ω = 1230 rpm = 1230 * 2π/60

= 128.8 rad/s

No. of turns N = 158

Magnetic field B = 3.81 * 10^-5 T

Area of coil A = π * r² = 3.14 * 0.125²

E_max = 0.038 V
