Magnets and Magnetic Fields Flashcards
What happens when the north poles of two magnets are brought close to one another?
The north poles of the magnets repel one another, because like poles repel.
True or false? Magnetic field lines always go from south to north.
False
Magnetic field lines always go from north to south
Magnetic field lines can be drawn to show the magnetic field of a bar magnet. At which points will the lines be closest together?
The magnetic field lines of a bar magnet are closest together at the poles. This shows that the magnetic field is strongest there.
When compasses are not near magnets, they all point north, why?
The Earth generates a magnetic field. The bar magnets inside the compass line up with it
Describe the magnetic field that is created between the north and south poles of two bar magnets when they are placed near each other.
A uniform magnetic field is created, which is the same strength and acts in the same direction everywhere between the poles. The field lines point from north to south.
