Question

A 4040-turn circular coil of radius 0.0500.050  m is in a magnetic field perpendicular to the coil. The field varies as B(t)=(0.30+2.0t2)B(t)=\$$left(0.30+2.0t^2$$\right) T. Calculate the magnitude of the induced electromotive force at t=1.5t=1.5 s.

A 4040-turn circular coil of radius 0.0500.050 m is in a magnetic field perpendicular to the coil. The field varies as B(t)=(0.30+2.0t2)B(t)=\(\left\)(0.30+2.0t^2\(\right\)) T. Calculate the magnitude of the induced electromotive force at t=1.5t=1.5 s.

A $40$ -turn circular coil of radius $0.050$ m is in a magnetic field perpendicular to the coil. The field varies as $B (t) = (0.30 + 2.0 t^{2})$ T. Calculate the magnitude of the induced electromotive force at $t equals 1.5$ s.
