1. When the magnet is pushed into the middle coil, ____________ as much voltage is induced as in the coil on the left?

2. When the magnet is pushed into the coil on the right, _________ as much voltage is induced as in the coil on the left?

3. Another name for the generator effect?
a. conservation of charge
b.Coulombs law
c. conservation of energy
d. law of induction

4. What effect would an iron core placed inside the primary and secondary coils have on magnetic fields and the galvanometer reading?

5. Why would transmitting electric energy at low voltages results in larg energy losses?

Help please! Chem/physics..?

1Current generated by induction in a generator, and the needle moving in a compass prove that:
A there is a current flowing through a compass.
B a compass can be used to produce electricity.
C magnetic fields can exert a force that have visible effects.
D electric fields are responsible for making a compass work.

2Generators use electromagnetic inductance to create current.

* What is electromagnetic inductance?
* How does a generator use electromagnetic inductance to create a current?

3A loop of wire is placed within a magnetic field. If the loop of wire is stationary as is the magnetic field, will a current be induced in the wire? Why or why not?
