a field is a region of space surrounding an object that can cause another object to experience a force
ex: gravitational field, electric field a magnetic field is a 3-D region of
space surrounding a magnet that will exert a force on magnetic objects

magnets have 2 ends (poles) unlike poles attract each other while
like poles repel each other the force of attraction or repulsion
increases as the magnets get closer to one another

earth has a magnetic field that exists both inside and surrounding it
when a magnet is free to rotate it will align itself with Earth’s magnetic field (compass)

magnetic fields exist in 3 dimensions surrounding a magnet and are more intense at the poles
they are invisible, but can be represented with field lines point from north to south pole outside a
magnet, and from south to north pole inside a magnet
never cross one another are close together where the magnetic field is
stronger

a compass can be used to map the direction of the field lines around a magnet
the needle will align itself along the direction of the field

when opposite poles of two magnets are brought near each other they attract
this happens because of the way the magnetic fields interact
![Page 9: a field is a region of space surrounding an object that can cause another object to experience a force ex: gravitational field, electric field a.](https://reader035.fdocuments.us/reader035/viewer/2022062600/5a4d1b567f8b9ab0599a98fe/html5/thumbnails/9.jpg)
when two like magnetic poles are brought near each other they repel
this also happens because of the way the fields interact
![Page 10: a field is a region of space surrounding an object that can cause another object to experience a force ex: gravitational field, electric field a.](https://reader035.fdocuments.us/reader035/viewer/2022062600/5a4d1b567f8b9ab0599a98fe/html5/thumbnails/10.jpg)
unlike poles attract
like poles repel

the bottom of the train is attracted upwards toward the bottom of the track
the guidance magnet keeps the train along a specific path
floats above track to reduce friction/increase speed
uses magnetic fields for levitation and forward motion

uses incredibly strong magnetic fields to produce very detailed images of the inside of the human body

magnetic fields cause forces on objects that can be affected by magnets
magnetic fields are three-dimensional magnetic forces increase as magnetic
objects get closer to each other magnetic fields cause attraction between
unlike poles and repulsion between like poles magnetic field lines represent what a
magnetic field looks like around a magnetic object
these lines point from north to south outside the magnet and south to north inside
the lines never cross one another the lines are close together where the field is
stronger
