Magnetism Flashcards
What are the two Laws of Magnetism
Magnets can exert force on to other magnets
Magnets can exert force onto unmagnetised magnetic material
When two north poles come close they…
Repel
When two south poles come close they…
Repel
When a North pole comes close to a south pole they…
Attract
Like poles…
Repel
Opposite poles…
Attract
Both poles will always [___] unmagnetised magnetic materials
Attract
What is the magnetic field
The space around a magnet where forces are felt is called is a magnetic field
What does a plotting compass help us to do
A plotting compass will allow us to draw clear, precise diagrammatic versions of photos
Which way will the arrow on a plotting compass point
In the direction of the magnetic force
What are the two things we can learn from a magnetic field diagram
The closer the field lines, the stronger the force (closest at poles)
The arrows give the direction of the force (North to south)
Just placing a bar magnet on your desk will not magically see it spin to point to magnetic north, explain why not
It is not free to move or rotate , as well as, friction is stopping it spin. A compass is a magnet which is free to move
What can we conclude from the experiment of making a permanent magnet, with these conclusions using the domain theory
Stroking a length of steel will permanently magnetise it
There are poles inside a magnet
What is a domain
A group of atoms with magnetic poles
How do we represent a domain
An arrow, with the tip being the north end
