30sS10FE-IIj-54 - Q2
Which principle works with an electric motor and generator respectively?
Faraday’s Law and Ampere’s Law
Fleming’s Right-Hand Rule and Electromagnetic induction
electromagnetic induction and current-carrying conductor inducing a magnetic field

30sS10FE-IIj-54 - Q3
Based on the principle of electromagnetic induction as applied to generators, which setup produces the greatest amount of electric current as a magnet is inserted into a coil of wire? Consider the same strength of the magnet.
A magnet is inserted into a coil with 100 turns of wire.
A magnet is inserted into a coil with 200 turns of wire.
A magnet is inserted into a coil with 250 turns of wire.
A magnet is inserted into a coil with 150 turns of wire.

What is the transfer of electricity in a motor?
chemical to mechanical
mechanical to electrical
kinetic to potential
electrical to mechanical
30sS10FE-IIj-54 - Q5
In a simple electric motor, like poles of the magnets repel and unlike poles of the magnets attract. This causes the coil to rotate and thus changes electrical energy to ________________energy
potential
mechanical
chemical
sound
