For example, you can see a magnet making another magnet - or certain magnetic materials, such as iron - move.
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
The magnetic field of a plate is characterized by its strength and direction. It can attract or repel magnetic materials and exert a force on charged particles. The effects of a magnetic field include inducing electric currents, aligning magnetic materials, and influencing the motion of charged particles.
A magnetic field is typically detected by observing its effects on magnetic materials such as iron filings or compass needles. Additionally, instruments like magnetometers can directly measure the strength and direction of a magnetic field.
One can see magnetic fields by using a device called a magnetic field viewer, which contains tiny particles that align with the magnetic field lines, making them visible to the human eye.
You can see the invisible magnetic field by using iron filings. When sprinkled around a magnet, the iron filings align themselves to the magnetic field lines, making the lines visible. This technique helps visualize the magnetic field's direction and strength.
The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.

No, magnetic fields do not extend out infinitely. They have a limited range of influence, determined by the strength of the magnetic source and the medium through which the field is propagating. Beyond a certain distance, the effects of the magnetic field become negligible.
The effects of Earth's magnetic properties are visible in the form of the auroras, caused by solar wind particles interacting with the magnetic field near the poles. The magnetic field also helps protect the Earth from harmful solar radiation and cosmic rays by deflecting these particles. Additionally, compass needles align with the Earth's magnetic field, allowing for navigation based on north and south poles.
A moving electric charge creates a magnetic field around it. This magnetic field interacts with other nearby magnetic fields and forces, leading to various electromagnetic effects such as electromagnetic induction or magnetic attraction/repulsion.
Doubling the current in a magnetic system will result in the magnetic field strength doubling as well. This increase in the magnetic field can cause a proportional increase in the magnetic force experienced by a nearby magnetic material or particle. Therefore, the magnetic effects in the system will be stronger when the current is doubled.
