Tiny Spinners
Like the Earth, electrons move in an orbit and do THIS on their own axis.
What is spin?
These are the "groups" where loner electrons hang out.
What are Domains?
This natural event can strike a rock and turn it into a magnet.
What is lightning?
Because magnets pull without touching, it is THIS kind of force.
What is a noncontact force?
These high-speed trains use repulsion to float above tracks.
What are Maglev trains?
This is the "rule" for any electron that spins.
What is it creates a tiny magnetic force.
In unmagnetized iron, the domains face in THESE directions.
What are random/different directions?
In a factory, metals are put inside THIS to align electrons.
What is a strong magnetic field?
North and North will do this, while North and South will do this.
What is repel and attract?
These tools use the Earth's magnetic field to find North.
What are compasses?
In most objects, electrons come in THESE, causing them to cancel out.
What are pairs?
A big magnet acts like this to make all the loners face the same way.
What is a "Boss" or "Big Mamma' or "Big Daddy"?
This flows through a wire to create a magnetic field.
What is electricity?
As this increases, the magnetic force gets weaker.
What is distance?
Doctors use these giant magnets to see inside the human body.
What are MRI machines?
These are the 3 specific metals that have "loner" electrons.
What are Iron, Nickel, and Cobalt?
This happens to domains in a permanent magnet so they stay aligned.
What is they are frozen/locked in place.
The Greek/Latin root "Ferro" in Ferromagnetic actually means this.
What is Iron?
A junkyard magnet is stronger than a fridge magnet because of THIS.
What is a higher number of Loners or loner electrons?
This specific part of a magnet has the strongest pull.
What are the poles?
This is why "paired" electrons don't create a magnetic pull.
What is yhey spin in opposite directions/cancel out.
This physical action can "jiggle or move" domains out of alignment.
What is hitting it or dropping it or heating it?
This final factory step "locks" the magnets in place.
What is cooling it down or freezing it?
Unlike gravity which only attracts, magnetism can also do THIS.
What is repulsion or repel?
If you break a bar magnet in half, you are left with THIS many poles.
What is two (a N and a S)?
