A square loop of wire 10cm on a side with 100 turns of wire rotates in a magnetic field, |B| = 0.01T, twenty times each second. At t = 0, the normal of the loop aligns with the magnetic field. Write a symbolic expression for the voltage as a function of time starting from Faraday’s Law. Define each symbol in your expression and give its numerical value. Calculate the peak output voltage of the generator.

Answer with Explanation:

We are given that

Side, l=10 cm=

1 m=100 cm

Magnetic field,B=0.01 T

Number of turns ,N=100

Magnetic flux,

By Faraday's law

Where =Angular frequency

N=Number of turns

B=Magnitude of magnetic field

A=Cross section area  of wire

For peak voltage

=

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
