The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...

It shows how iron filings reveal the magnetic field around a magnet, how charged objects create electric fields that can attract materials, and how gravity creates a gravitational field that pulls ...

it produces its own magnetic field the magnetic field cannot be turned on and off - it is there all the time Bar magnets and horseshoe magnets are examples of permanent magnets. An iron rod placed ...

That’s the subtle magnetic force—generated by the planet’s molten metal core—that surrounds Earth, not unlike the force around a bar magnet. The intensity and direction of the field vary ...

Such a magnet has opposing magnetic moments, but has a non-zero spontaneous magnetization in zero magnetic field. When they placed a ferrimagnet on top of their superconductor and created a magnetic ...

Because Earth's magnetic field is slightly asymmetrical and more complex than that of a regular bar magnet, the magnetic south pole — the point in the Southern Hemisphere where the magnetic ...

Image Source: NCERT Textbook Figure (a) shows the magnetic field lines a bar magnet and figure (b) shows magnetic field due to a current-carrying finite solenoid The larger the number of field ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...
