What are magnetic field lines?
Click to flip
Magnetic field lines are visual representations of the magnetic field strength and direction around a magnet.
Click to flip
How do the field lines around a bar magnet appear?
Click to flip
The field lines emerge from the north pole and loop around to enter the south pole.
Click to flip
Do magnetic field lines intersect?
Click to flip
No, magnetic field lines never intersect.
Click to flip
What does the spacing between magnetic field lines indicate?
Click to flip
The spacing indicates the strength of the magnetic field – closer lines mean a stronger field, wider lines a weaker field.
Click to flip
How are the earth's magnetic field lines oriented?
Click to flip
They run from geographic south to north, which aligns with the earth's magnetic north and south poles.
Click to flip
Why are iron filings used to show magnetic fields?
Click to flip
Iron filings align themselves along the magnetic field lines, visually showing the field's shape and pattern.
Click to flip
What happens to magnetic field lines inside a magnet?
Click to flip
Inside a magnet, field lines move from the south pole to the north pole.
Click to flip
Can we see magnetic field lines?
Click to flip
No, magnetic field lines are invisible; we can only see their effects.
Click to flip
What effect do magnetic materials have on field lines?
Click to flip
Magnetic materials can alter the direction and concentration of magnetic field lines.
Click to flip
In which direction do magnetic field lines flow in relation to the earth?
Click to flip
Earth's magnetic field lines flow from the northern hemisphere to the southern hemisphere externally.
Click to flip
Why is the concept of magnetic field important?
Click to flip
It helps in understanding and predicting the behavior of magnetic forces around magnets and currents.
Click to flip
How does a compass work with magnetic field lines?
Click to flip
The needle aligns itself along the Earth's magnetic field lines, pointing toward the magnetic poles.
Click to flip
What visual characteristics do uniform field lines show?
Click to flip
Uniform field lines are parallel and evenly spaced.
Click to flip
What is the significance of north to south direction in field lines?
Click to flip
It defines the conventional direction of magnetic fields outside a magnet.
Click to flip
What happens when two magnetic fields interact?
Click to flip
They can combine in ways that either strengthen or weaken specific regions based on their alignment.
