What is the role of permanent magnets in a speaker?
The electromagnet is positioned in a constant magnetic field created by a permanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole. When the electromagnet's polar orientation switches, so does the direction of repulsion and attraction. In this way, the alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet. This pushes the coil back and forth rapidly, like a piston.
Why does friction increase as the speed increases?
because the forces creating the friction are rub faster(harder).
What increases when the gravitational forces increase?
the gravitational forces.Answer:As mass increases the gravitational force increases. Also, as the nearness of the objects increases the gravitational force increases, but this is usually thought of as the distance between the objects decreasing
What is some examples of long range force?
Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.
How is contact forces and mechanical forces different from gravitational and magnetic forces?
because your ugly
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.

When do the frictional forces between two surfaces increase?
As they come into contact so tight friction would increase As roughness increases frictional force too increases.
What determines the strength of dispersion forces?
London dispersion forces are dependent on the motion of electrons, their strength increases with the number of electrons in the interacting atoms or molecules. This means that London forces increase as the atomic or molar mass increases.
Why does friction increase as the speed increases?
because the forces creating the friction are rub faster(harder).
How can the magnetic field strength of an electromagnet be reduced?
Either increasing the size of the current (in amps) or the number of turns of wire wrapped around the core will make a stronger magnet. A larger current will make a stronger magnet (up until too much makes the wire melt!). Increasing the voltage forces more current through the electromagnet.

What are magnetic forces used for in everyday life?
magnetic forces are used in magnetic poles
When mass increases its gravitational force decreases right?
Wrong. When the mass of either or both objects increases, then the forces of gravitational attraction between them also increase.
Is a negative object attracting a neutral object considered magnetism?
"Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Where are the magnetic forces the strongest?
magnetic poles
