Permanent And Induced Magnets Flashcards
What do all magnets produce
Magnetic field- a region where other magnets or magnetic materials (iron, steel, cobalt, and nickel) experience a non contact force
How can you show a magnetic field
Drawing magnetic field lines
The lines go from north to south and show which way a force would act
What does it mean when the lines are closer together
The stronger the magnetic field
What does it mean when the lines are further away
Weaker the field
Where is the magnetic field strongest
At the poles
What charge is the force between a magnet and a magnetic material
Always attractive
What happens if two permanent magnets are put near each other
They will exert a force on each other
It can be attractive or repulsive
What do compasses show
Directions of magnetic fields
What are permanent magnets
Produce their own magnetic field
What are induced magnets
Magnetic materials that turn into a magnet when they’re put into a magnetic field
Induced poles
What is the force between permanent and induced magnets
Attractive
What happens when you take away the magnetic field
Induced magnets quickly lose their magnetism and stop producing a magnetic field
What does the strength of the magnetic field depend on
The distance from the magnet
What does the compass contain
A small bar magnet. The earth has a magnetic field. The compass needle points in the direction of the Earth’s magnetic field
