Forms of electricty
What is magnetic energy
the potential energy stored within a magnetic field
A tool used to find the Earth’s north pole. There is a needle that can spin freely that is attracted to the North.
Compass
includes heat, light and/or mechanical energy
Electrical energy
created when a wire is wrapped around certain iron bearing metals (iron nail) to form a closed circuit that electricity is passed through. The electricity produces a magnetic field in the wire and the magnetic field is transferred to the iron nail, making it a temporary magnet.
Electromagnet
is lightning a form of static electricity
Yes
What is electrical circuits
energy through a transmiting path
to be pulled toward an object by an invisible magnetic force
Attract
the negative particles of an atom that orbit around the nucleus. This symbol (-) signifies a negative charge. The continuous flow of electrons creates electric currents.
Electrons
To make an electromagnet stronger you want to
use an iron nail. The larger the nail (or bolt) the stronger the magnetic field.
What causes a charged ballon to stick on a wall
static electrcity
what is electrical magnetic
the phenomenon where electricity and magnetism are interconnected
the space around the magnet within which the force of the magnet can act
Magnetic Field
created by rubbing certain materials together.
Static electricity
To make an electromagnet stronger you want to:
add more coils around the iron nail or bolt and make the coils close together
What is the feeling called when you get a spike in your body from someone else, and how is it cause
what is static electricty
a buildup of electrical charge on the surface of an object
the invisible force that attracts objects containing iron, nickel, and cobalt
Magnetism
the path along which negative charges can flow
Electric circuit
To make an electromagnet stronger you want to
increase the battery voltage (use a bigger battery with more power)
if i rub a ballon on my shirt and stick on my hair it will stick because
The charged up of static electricty
what is electrcity
the flow of electrons, which creates a charge that can be used to power devices
the act of one object being pushed away from another object
Repel
the amount of opposition that a material gives to the flow of electric current (slows down electric current)
Resistance
Electromagnets are used in many different materials such as
MRI machines (in hospitals)
Speakers
Washing Machines
Motors
Generators
What are the two main types of static electricty
volumetric and surface
