Question

A closely wound rectangular coil of 75.0 turns has dimensions of 22.0 cm by 45.0 cm . The plane of the coil is rotated from a position where it makes an angle of 36.0 ° with a magnetic field of 1.00 T to a position perpendicular to the field. The rotation takes 6.00×10^−2 s .

Answer 1

Answer:51.52 V

Step-by-step explanation:

Given

N=75 turns

`Area=22* 45 cm^2`

`\theta =36^(\circ)`

`Emf induced =-N\frac{\mathrm{d}\phi }{\mathrm{d} t}`

`Emf=-75A(B_2-B_1)/(t)`

`Emf=-75* 22* 45* 10^(-4)(1(1-cos(90-36)))/(6* 10^(-2))`

Emf=51.52 V
