Calculating the Induced EMF
- Given parameters:
- Number of spokes, N = 20
- Length of each spoke, l = 1m
- Angular velocity, ω = 120 rpm = 120 * 2π / 60 rad/s = 4π rad/s
- Magnetic field, B = 0.4G = 0.4 * 10^-4 T
Calculating the Magnetic Flux
- Magnetic flux through each spoke:
Φ = B * A = B * l * d = B * l^2
where d is the diameter of the wheel which is equal to l in this case.
- Total magnetic flux through all spokes:
Φ_total = N * Φ = N * B * l^2
Calculating the Induced EMF
- The induced EMF is given by:
ε = -dΦ/dt
- Substituting the values:
ε = -d(N * B * l^2)/dt
ε = -N * l^2 * dB/dt
- Since the magnetic field is constant, dB/dt = 0
Therefore, ε = 0
Hence, the induced EMF between the axle and rim of the wheel will be zero in this scenario.
