What happens if you force magnets together?
In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).
Why do the iron filings near the bar magnet seem to align in the shape of closed curves?
Answer. A magnetograph can be created by placing a piece of paper over a magnet and sprinkling the paper with iron filings. The particles align themselves with the lines of magnetic force produced by the magnet.
Why do iron filings arrange themselves in a pattern?
The magnet exerts its influence in the region surrounding it. Therefore the iron filings experience a force. The force thus exerted makes iron filings to arrange in a pattern. The lines along which the iron filings align themselves represent magnetic field lines.
What happens when iron filings are sprinkled around a bar magnet?
When the iron filings are sprinkled, those very close to the magnet, where the magnetic force is the strongest, will cling to the magnet. Those filings a little farther away, where the magnetic force is less strong, will align themselves with the magnetic flux lines, but they will not be drawn to cling to the magnet.
Why do the iron filings arrange in such a pattern?
The iron fillings arrange themselves in a pattern because they get attracted by the bar magnet. The pattern that they form can also be called the magnetic field lines of the bar magnet.
What is the direction of magnetic field inside the magnet?
By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials. As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material.
What are magnetic field lines Class 10th?
Magnetic field lines: Magnetic field lines are imaginary lines around the magnet. The magnitude of a field is indicated by its line’s density. Near to South and North Pole of a magnet, the magnetic field is stronger and will get weaker when it moves away from the poles.
What is meant by magnetic field Class 6?
The force of attraction around a magnet, which is maximum at the poles (ends) of the magnet, is called magnetism. The area around a magnet where the magnet’s forces work is called the magnetic field. In simple words , a magnet is a object which produces a magnetic field.
What is the formula for Tesla?
The tesla (symbol: T) is a derived unit of the magnetic B-field strength (also, magnetic flux density) in the International System of Units. One tesla is equal to one weber per square metre….Tesla (unit)

What types of materials do magnets attract?
Magnets are only attracted to special metals. Iron, cobalt and nickel are magnetic. Metals that have iron in them attract magnets well. Steel is one.
