a student makes a simple generator by using a single sq. loop 10 cm on each side. the loop is then rotated at a frequency of 60Hz in a magnetic field of 0.015T.
What is the max emf output? what would be the max emf output if 10 such loops were used instead?
The formula is
emf = NBAω = NBA(2πf) = 1*.015*(.1*.1)(2π*60)
emf = .0565 V
Clearly, 10 loops would produce 10 times the emf......
