P7- Magnetism And Electromagnetism [2] Flashcards
Name the two poles of a magnetic
South and north
How does a magnetic force effect other magnetic materials
Causes induced magnetism or experience a non contact force
What does close the lines on a magnetic field figure mean
Stronger the magnetic field
Where is a magnetic field strongest
At either pole
What do the same poles near do
Repel
What do the opposite poles near do
Attract
Why does a compass always point north
Because the earth generates its own magnetic field
What do permanent magnetic produce
Their own magnetic field
What is the force between a magnet and an induced magnet
Always Attract
What is a solenoid
A coil of wire with a current sent through
What does a solenoid do
Increase magnetic field strength
How do you find out the end of the solenoids pole
The right-hand rule
What does a change of the direction of the current
Change of the direction of the magnetic fields
The larger the current through the wire
The stronger the magnetic field
What is a magnetic that can be turned on and off called
Electromagnet
