magnet
What is a Magnet
any material capable of attacking iron and producing a magnetic field outside itself
What is magnetic force
Magnetic force is the force a magnet exerts on another magnet on iron or similar metal or on moving charges
What is a magnetic field
a vector field in the neighbourhood of a magnet electric current or changing electric field in which magnetic forces are observable
what is the shape of the Earth´s Magnetic field what causes this filed
The uneven flows and distributions of the molten metals that generate Earth's field cause the field to be quite lumpy
What is the iron rule
has a valuable by-product, and that by-product is data
if you cut a magnet in half, you have
two magnets
How does a magnetic force work
The force generated by the aligned atoms creates a magnetic field
What are magnetic field lines and what direction do they run
outside the magnetic field lines run north to south. Inside they run from south to north
What formed the earth
gravity pulled swirling gas and dust in to become the third planet from the Sun
When is the last day of school
June 28th
How do you think distance affects the way magnets poles
Explain how moving charges make magnetic field and moving magnetic field make current or charges move
When an electrical charge is moving or an electric current passes through a wire, a circular magnetic field is created
What produces a magnetic field that has the same shape as a bar magnet
Earth
What is Earth's nickname
Blue Planet
What grade are you guys be in 3 years
12th grade
What do magnets do to a paperclip?
the paperclips can become temporarily magnetized
Describe what happens to the fields of two bar magnets when you bring their north poles together
the magnetic field lines will bend away from each other
Do magnetic fields lines have a direction?
from North to South
how long does the earth take to orbit the sun
365 days
What is a switch the opens when a current is to high?
circuit breaker
How many types of magnets are there
three
What 2 things can happen to a magnet entering a magnetic field
repel or attract
Where is the field of a magnet strongest
near both poles
How many times does the Earth go around the sun in a year
once a year
What are magnetic domains
A domain is a region inside of a material where groups of magnetic moments naturally align in the same direction
