Question 1

Lines of force are more dense the closer you are to the poles​ (T or F)

Answer 1

True

Question 2

What are the 6 Characteristics of Magnetic Lines of Force ​?

Answer 2

Magnetic Lines of force possess direction

Magnetic lines of force always from complete loops ​

​
Magnetic lines of force represent tension along their length that tends to make them as short as possible

Magnetic lines of force repel each other

Magnetic lines of force cannot intersect or cross, but must always form individual loops.

Magnetic lines of force always tend to arrange themselves in such a manner that the maximum number of lines of force are set up

Question 3

what is reluctance?

Answer 3

Property that opposes the setting up of flux lines is known as Reluctance​

Question 4

How does magnetism by induction work?

Answer 4

When a magnet is held up to a ferromagnetic material which causes the creating poles in that material.

Question 5

Common Methods of Producing Artificial Magnets ​

Answer 5

Using Electric Current is the most effective way of producing an artificial magnet ​

A magnetic field is produced every time current flows through a conductor​

You can significantly increase the magnetic field if the conductor is wound into a coil and wrapped around a piece of ferromagnetic material ​

Question 6

Common Methods of Demagnetizing Ferromagnetic Materials ​

Answer 6

Using Electric Current ​
Apply an alternating current to the object and slowing remove the object from the magnetic field or slowing turning down the current ​

Using Heat ​
Bring the temporary magnet up to its Currie Temperature, for iron this is 770 degrees Celsius​

Using Vibration ​

Question 7

What item can be used to prevent magnets from getting damaged when stored

Answer 7

Keepers
