1 a circular coil with one turn is in a perpendicular time, Ask an Expert

Academics

1) A circular coil with one turn is in a perpendicular (time dependent) magnetic field given by B = 1.400 - 0.0500 t Tesla, where time t is in seconds. The induced voltage in the loop is 3.03V. Calculate the radius of the coil.

2) A different 230 turn conducting coil with a radius of 10.7cm rotates at a frequency of f = 65.0Hz in a magnetic field B = 0.160T. Calculate the generated rms emf. The rms (root-mean-square) value of a sinusoidal quantity is the amplitude divided by root of 2.
