Magnetic Forces Flashcards
What happens to the force between magnetic poles depending on polarity and separation?
Like poles (N-N or S-S) repel each other.
Unlike poles (N-S) attract each other.
The force between magnets increases as the poles get closer and decreases as they move apart.
How can you investigate the forces between like and unlike poles
Use two strong magnets:
Place like poles (e.g., N-N or S-S) near each other — they will repel.
Place unlike poles (e.g., N-S) near each other — they will attract.
Force will be stronger the closer the poles are.
What is a magnetic field
A magnetic field is a region around a magnet where magnetic forces can be felt. It is represented by magnetic field lines, which show the direction of the force.
What do magnetic field lines indicate
Magnetic field lines show the direction of the magnetic force acting on an N-pole.
The lines point outward from the North pole and inward to the South pole.
The closer the lines, the stronger the magnetic field.
