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 .

Respuesta :

Answer:51.52 V

Explanation:

Given

N=75 turns

[tex]Area=22\times 45 cm^2[/tex]

[tex]\theta =36^{\circ}[/tex]

[tex]Emf induced =-N\frac{\mathrm{d}\phi }{\mathrm{d} t}[/tex]

[tex]Emf=-75A\frac{B_2-B_1}{t}[/tex]

[tex]Emf=-75\times 22\times 45\times 10^{-4}\frac{1(1-cos(90-36))}{6\times 10^{-2}}[/tex]

Emf=51.52 V
