Write a short notes on magnetic field?
A magnetic field is an invisible force field generated by moving electric charges, such as electrons. It exerts a force on other moving charges and magnetic materials. Magnetic fields are represented by field lines that show the direction and strength of the field. They are characterized by their direction, intensity, and polarity.
What is a magnetic field explanation for kids?
Well... you could visually demonstrate a magnetic field. Kids like visual learning tools. You can get a big magnet and put a piece of paper over it. Then take some type of metal filings and sprinkle them over the paper. The metal filings will align themselves in the direction of the magnetic field. You can explain to them about north and south poles. How the magnetic field is attracted to the south pole. Also take a compass and bring it close to the paper and you will see the compass moving in the direction that your sprinkled metal filings have fallen.
What are invisible magnetic lines that leave the north pole and enter the south pole of the magnet called?
because the north pole always try's attracts the south pole so that is why the visible magnetic lines of poles are from north tosouth
What part of the magnetic field is strongest and what part is the weakest?
The magnetic field is strongest at the poles of a magnet, where the magnetic field lines are most concentrated and closely packed. The magnetic field is weakest in the areas between the poles, known as the equator of the magnet.
What invisible force does the mineral lodestone have?
The mineral lodestone, also known as magnetite, is ferromagnetic, which means that it can be magnetized. Most of the magnetite found on Earth was magnetized by the Earth's magnetic field as the magnetite formed. Most naturally occurring lodestones are magnetized, but the strength of that magnetization is much less than any common magnet and can only be detected with sophisticated equipment. The invisible force is... magnetism.
What is the invisible force around a magnet called?
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
What is the invisible area where the forces of magnetic attraction or repulsion can be detected?
The magnetic field is the invisible area where the forces of magnetic attraction or repulsion can be detected. This field extends around a magnet and can exert forces on other magnetic objects within its influence.
How can iron filings be used to demonstrate magnetic field lines?
Iron filings can be used to demonstrate magnetic field lines by sprinkling them around a magnet. The filings align along the magnetic field lines, making the invisible magnetic field visible.
What is the purpose of the field magnet?
A magnetic field is the invisible field of magnetic force that is exerted on substances that are sensitive to magnetism. Magnetic fields have been studied by scientists and are used in applications such as compasses and MRI equipment.
What surrounds a magnet?
A magnetic field.
What does a magnetic field look like?
A magnetic field is invisible, but its presence can be detected by placing a compass near a magnet. The magnetic field lines around a magnet are depicted as flowing from one pole to the other, forming a looped shape. The strength of the magnetic field is strongest near the poles of the magnet and weakest at its center.
Can you feel or hear the magnetic field?
No, humans cannot physically feel or hear a magnetic field. Magnetic fields are typically invisible and do not produce any sound that the human ear can detect. However, specialized equipment can detect and measure magnetic fields.
How does a bar magnet interact with its surroundings to create magnetic field lines?
A bar magnet interacts with its surroundings by creating a magnetic field around itself. This magnetic field is represented by invisible lines that extend from the magnet's north pole to its south pole. These field lines show the direction and strength of the magnetic force exerted by the magnet.
What is a magnetic field made of and how does it interact with other objects?
A magnetic field is made of invisible lines of force that surround a magnet or electric current. It interacts with other objects by exerting a force on them, either attracting or repelling them depending on their magnetic properties.

A magnetic field is an invisible force field generated by moving electric charges, such as electrons. It exerts a force on other moving charges and magnetic materials. Magnetic fields are represented by field lines that show the direction and strength of the field. They are characterized by their direction, intensity, and polarity.
How can one see magnetic fields?
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.
What do you sprinkle on a magnetic field to see it?
iron fillings
