How can a chunk of ferro magnetic material be magnetized in the laboratory?
By putting it inside a magnetic field
By putting it inside a gravitational field
By putting it inside a nuclear field
By putting it inside an electric field
What happens when an external magnetic field is applied to a chunk of ferro magnetic material?
It eliminates a lot of the magnetic domains
It creates more magnetic domains
It changes the size of the magnetic domains
It has no effect on the magnetic domains
What is the overall behavior of a magnet determined by?
The temperature of the magnetic domains
The size of the magnetic domains
The alignment of the magnetic domains
The color of the magnetic domains
What is the purpose of using magneto static energy in a magnet?
To create giant magnetic fields around the magnet
To reduce the amount of energy
To increase the amount of energy
To change the direction of the magnetic domains
How do magnetic domains lead to the overall behavior of the magnet?
By aligning to create an overall magnetic field
By pointing in every which direction
By changing their size
By separating from each other
