Example of magnetic fields
Iron , steel, nickel and cobalt
What happens when a north magnet goes to another north magnet
They will repel
What happens if it goes south to north
They will attract
What happens if the magnetic field line is close

What are permanent magnets
Magnets that produce its own magnetic field
What are induced magnets

What happens when u take away the magnetic field
Induced magnets quickly lose most of there magnetism
What are the force between permanent and induced
They always attractive
What is a solenoid
Wrapping wire into coil
How do u increase the strength of a magnetic field
Wrapping the wire into a coil
Describe the magnetic field inside a solenoid
It’s is very strong
