Suppose the loop in Exercies.4 is stationary but the current feeding the electromagnetic net that produces the magnetic field is gradually reduced so that the field decreases from its initial value of 0.3 T at the rate of 0.02 T s^(-1). If the cut is joined and the loop has a resistance of 1.6Omega, how much power is dissipated by the loop as heat? What is the source of this power?

Answer»

Solution :Here ν = 0.5 Hz, N =100, A = 0.1 `m^2`and B = 0.01 T. Employing EQ.
Eq. (6.21)
`epsi_0 = NBA (2PI V)`
`=100xx 0.01xx0.1xx2xx3.14xx0.5`
`=0.314V`
The maximum voltage is 0.314 V
We URGE you to explore such alternative possibilities for power generation.
