Electrical Forces
force between two electrically charged objects that are close to each other
electric force
the ability to do work
energy
a device consisting of an iron or steel core which magnetizes by an electrical current running through a wire coil surrounding the core
electromagnet
the movement of electrons on an electrical circuit
electrical energy
This item used magnetic force to find directions
compass
property of an object or particle that causes it to experience force when it is in an electric or magnetic field
electric charge
a path or line through which electric current flows
electric circuit
force of repulsion or attraction between moving charged particles
magnetic force
the rate of flow of electric charge past a point or region
electric current
Iron or Steel
The strength of electric force if object one is +1 and object two is -1
weak
the conversion of one form of energy to another, or the movement of energy from one place to another
energy transfer
What will happen to the magnetic force if the current traveling through the coil of an electromagnet is increased?
It will increase
materials that allow electric current to pass through them easily
conductors
This can make copper ( a non magnetic metal) magnetic
Using electric current to create the magnetic field
The strength of electric force if object one is +2 and object two is -2
medium
the process of changing an energy type to another
energy transformation
What will happen to the magnetic force is the amount of coils on an electromagnet are increased?
it will increase
materials that resist the flow of electric current
insulators
Why could you shut off an electromagnet?
to let go of object picked up by the magnet
The electric force is stronger/weaker as the distance between object one and object two increases.
weaker
energy cannot be created or destroyed, but changed from one form to another
law of conservation of energy
If the magnetic force of an electromagnet is low, how can it be increased?
More coil or higher current
measure of the opposition to current flow in an electrical circuit
resistors
This is how a magnetic field is produced
running a current through a conductor
