True/False
Electric current produces a magnetic field when it flows through a wire.
TRUE
"A flow of electrical charged through a conductor"
Electrical current
Who discovered the relation between electricity and magnetism?
Oersted
up of atoms made is matter All.
All matter is made up of atoms.
FALSE
"A circular shape, like a spring"
A loop.
What causes the magnetosphere?
The centre of the Earth made of liquid iron.
Electrons are particles that orbit the nucleus.
FALSE, BY OESTERD.
"The area around a magnet that has magnetic force"
Magnetic field
How can we identify a magnet?
Magnets attract other magnets or repel other magnets.
only flow Electrons if terminals these joined are conductor a by.
Electrons only flow if these terminals are joined by a conductor.
TRUE
"A simple motor that consist of a magnet that rotates within a coil or wire, the rotating magnet produces an electric current in the wire. It changes kinetic energy to electrical energy"
Dynamo
What is and electrical circuit? How does it work?
It's a continuous circle from the battery, through the components and back to the battery. When the electric current is flowing the light/lamp lights up.
stable in a atom In, the number positive of negative elcetrons and the is same.
In a stable atom, the number of positive and negative electrons is the same.
