The area around an object that is affected by the magnetism of that object is the?
A Magnetic Force
What are the lines called that the map out the magnetic field around a magnet?
They are called the magnetic field lines.
What is the space all around a magnet called?
I'm sure you mean the magnetic field
What do you call the force around a magnet?
the area of magnetic force around a magnet is called the magnetic field
How are the uses of an electromagnet different from those of a permanent bar magnet?
A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.
Can a round magnet produce electricity if it's rotating?
The shape of the magnet is unimportant. Any moving magnet can induce a voltage in a wire. Or any changing magnetic field. If the magnet rotates, its magnetic field will change, so yes.
What is the area around a magnet called?
magnetic field
Why does an electro magnet work?
Magnetizm and electricity are closly related. An electric current can produce its own magnetic field. Electricity can also be used to create a magnet. such magnets are called electromagnets. The electricity flowing through the tight coils of wire creates a strong magnetic fields from one end to the other. By running the electric current through a wire you can create a magnetic field. The force lines up all the magnetic particles in the nail and turns it into a magnet. The more coils of wire there are , the stronger the magnetic force.
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
Why can magnets attract objects without touching them?
Magnets have a magnetic field about them. This field can act on objects without the magnet coming in contact with the object.
What is difference between of Electromagnet and Electric Magnetic Field?
An electromagnet is a magnet that only generates magnetic forces when electricity is running through it, basically a magnet that can be turned on and off. An electromagnetic field is the magnetic force generated when an electromagnet is used.
The space in which the force of a magnet can act is called a?
magnetic field
