A very large loop of metal wire with radius 1 meter is driven with a linearly increasing current at a rate of 200 amps/second. A very small metal wire loop with radius 5 centimeter is positioned a small distance away with its center on the same axis (the loops are coaxial). The small loop experiences an induced emf of 983 nano-volts. What is the separation of the loops in meters?

    Sorry, as a teacher I'm opposed to giving you answers to homework questions because that's called helping you cheat.

    I will however help you figure out the answer. Question 1 is a logic question. don't read to much into it. if you still have problems figuring out what a first and 2nd level consumer is draw the action of a kestrel eating a mouse that's eating grass.

    After reading further I realize that all of these questions and answers are found in any basic Physics textbook. Actually, this seems like a take home test. I'm sorry but its against my ethics to go any further.

    In future, please provide your answers and then we can tell you if you're right or on the wrong path.
