Relationship Between Magnetic, Gravitational and Electric Fields (Middle School)
Transcript of Relationship Between Magnetic, Gravitational and Electric Fields (Middle School)
The strength of field is directly proportional the mass of the two objects. The more mass an object has, the greater the gravitational pull.
Magnetic fields exist around magnetic objects
If a second magnetic object is placed in the field, the two objects experience magnetic forces that can attract or repel them
Magnetic force weakens rapidly with increasing distance
Magnetic field lines can be seen when iron filings are sprinkled around a magnet
Gravitational Fields exist around objects with a mass
If a second object is placed in the field, the two objects experience attractive gravitational force toward each other
Gravitational force weakens rapidly with increasing distance
Electric fields exist around objects with charge
If a second object is placed in the field, the two objects experience electric forces that can attract or repel them
As distance increases, electric forces decreases
A field model is used to explain how objects can exert forces on each other without touching
The region around an object that it can influence is called a field
When a second object is placed in this region, the field exerts a force on and can cause changes in the motion of an object.
This influence is called "action at a distance"
