The direction of the magnetic field is determined by the direction in which a north pole of a compass needle moves inside it. Conventionally, it is established that magnetic field lines emerge from the north pole and merge at the ...

Yes, magnetic field lines around a bar magnet can be obtained by drawing them. It is possible to manually represent the magnetic field lines through observation and illustration.

The observed pattern of iron filings represents the magnetic field of the magnet. The region surrounding a magnet, where the force of the magnet is detected, is termed the magnetic field.

Iron filings arrange in a pattern around a magnet because the magnet exerts a force in the region surrounding it. The force influences the iron filings, causing them to align in a particular pattern.

Like poles of magnets repel each other, while unlike poles attract.
