Magnetism

Multiple Choice

Answer all the Multiple Choice Questions then hit "Check" after the last multiple choice question

The area around a magnet where the force of magnetism acts is called the?
magnetic domain
magnetic pole
magnetic field
turbine


A moving electric charge creates ___________.
a magnetic field
an alternating current
a turbine
magnetic domain


Which of the following makes an electromagnet stronger?
increasing current
adding more loops of wire
inserting an iron core
all of the above


Why does dropping a permanent magnet cause it to lose some of it's magnetism?
The North Pole of the magnet breaks off
The magnetic domains become aligned.
the magnetic domains become randomly arranged
The South Pole of the magnet breaks off.


Which of the following can also cause a magnet to lose it's magnetic properties
freezing it
heating it up to a high temperature
hitting it on a desk
both A and B
both B and C


What would happen if you broke a bar magnet in half?
one magnet would have a North Pole, and the other would have a South Pole
both magnets would have a north pole, but no South pole
both magnets would have a south pole, but no North Pole
both magnets would have a North Pole and a South Pole


Electromagnets are useful because:
the strength of it can be easily controlled
because they work only when electricity is flowing through the wire
both A and B
neither A nor B


Moving a loop of wire through a magnetic field _____________?
produces a magnetic field
creates a turbine
produces a current through the wire
causes no change at all


A device that makes electrical energy out of mechanical energy is called
an electromagnet
a generator
an electric motor
a transformer


If a Transformer has more loops on the primary coil than on the secondary coil is called a
Step up transformer
step down transformer
step through tranformer
turbine


A device that makes mechanical energy out of electrical energy is called
an electromagnet
a generator
an electric motor
a transformer


Which of the following is not true about a generator
it produces alternating current
often use water, steam or wind to turn the turbine
A coil of wire wrapped around an iron core rotates in a magnetic field
it produces direct current


Which of the following is not true about a transformer
one side will have more loops of wire than the other
it can only work with alternating current
it can increase or decrease the amount of voltage in the wire
all of the above are correct about Transformers
