5 Questions of Magnetism (Pages 53 to 55)

Question 1

Q: What are transformer used for?

C1: Transformers are used to increase or decrease
the amount of voltage coming in from the input

C2: It is used as a magnet.

C3: It is used to produce MRI images

Question 2

Q: How is a superconductor used in a particle accelerator?

C1: It is used to accelerate the particles.

C2: It is used by having large electric currents can flow through
electromagnets made from superconducting and can produce
an extremely strong magnetic fields.

C3: The ways of using the superconductors are not discovered yet

Question 3

Q: How are electric charges and magnets related to each other?

C1. They both like chicken.

C2. This enables electric motors and generators to operate.

C3. They both have a magnetic field.

Question 4

Q:What is the difference between a superconductor and a conductor?

C1. Superconductors are 63% made out of atoms

, but conductors are 80% made out of atoms

C2. Superconductors have no resistances to the flow

of electrons, but conductors do

C3. Superconductors have another name called
the supermagnet, but conductors dont


Question 5

Q: Which is not an advantage for using superconductors as electric transmission lines?

C1: a great conductor

C2: No heat is produced

C3: Lasts longer than other conductors



Question 6

Q: Which is a disadvantage for using superconductors as electric transmission lines?

C1: Superconductors can make magnets float above it

C2: Superconducters are too cold for the electricity to flow through

C3: Superconductors are always shifting around due to it's magnetic field
