p4 Flashcards
At which part of a magnet are the magnetic force strongest
The poles of the magnet
What happens when two magnets are brought close together
They exert a force on each other
What type of force is exerted if two like poles of a magnet are brought close together
A repulsive non contact force
What type of force is exerted if two unlike poles of a magnet are brought close together
An attractive non contact force
What is difference between permanent magnet and an induced magnet
A permanent magnet produces its own magnetic field
What is an induced magnet
An induced magnet becomes magnetic when plaved in a magnetic field
What type of force does an induced magnetism always cause
A force of attraction
What happens when an induced magnet is removed from a magnetic field
The induced magnet looses all of its magnetism
What is magnetic field
The region surrounding a magnet where another magnet or magnetic material experiences a non contacr force
Give 4 examples of magnetic material
- Iron
- Stee
- Colbalt
- Nickel
What can always be said about the force between a magnet and a magnetic material
It is always attractive
Ho does the strength of a magnetic field alter as tou move futher from the magnet producing it
The magnetic field strength decreases the futher you move away
In what direction does magnetic field point
. Direction that a north pole would experience a force if placed in the field
. From the north seeking pole to south seeking pole of a magnet
What does a magnetic compass contain
A small bar magnet that points in the direction of the earth’s magnetic field
What is produced when current flows through a conducting wire
A magnetic field is produced around the wire
