What do you notice about the iron filings?
All magnets show properties of magnetic attraction and repulsion. With the use of iron filings, we can see these magnetic fields. When iron filings are sprinkled on a bar magnet, you see that these magnetic field lines start at the magnet’s north end and will end at the magnet’s south end.
Where do the maximum iron filings get attracted in a magnet?
The magnetism of a bar magnet is maximum at its two poles and minimum in the middle. Hence, maximum iron filings will stick at the two ends of the magnet and minimum in the middle.
Which direction does this point to when a loose hanging magnet is fixed?
SOLUTION: A freely suspended bar magnet always comes to rest in the North-South direction. The geographical North facing end of the magnet is its north pole and the geographical south facing end is its South pole….Fun with Magnets – NCERT – NCERT Questions.

How can we convert an iron strip into a magnet?
An iron strip can be converted into a magnet by the following method: Place the iron strip on a table. Place one pole of a bar magnet near one end of the iron strip. Move the bar magnet along the length of the iron strip starting from one end to the other end as shown in the following figure.
What substance is attracted to a magnet?
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
What makes two magnet attract?
When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
What part of the magnet is the strongest?
pole
What are the names given to the two ends of a magnet?
A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. We say the magnets repel each other.
What is the name given to the two ends of a magnet where the attraction is strongest?
Poles
Where is the weakest part of a magnetic field?
The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.
Is there a camera that can see magnetic fields?
Fraunhofer scientists have developed a high-resolution magnetic line camera to measure magnetic fields in real time. Field lines in magnetic systems such as generators or motors, which are invisible to the human eye, can be made visible using this camera.
