# data[].attributes.body
The force between two magnets increases as magnets move closer tgetherand decreases as the magnets move farther apart

# data[].attributes.body
The fields lines that are closer together indicate a stronf magnetic field.

# data[].attributes.body
Is strongest a the end and all magnetic have north pole and south pole

# data[].attributes.body
Always points away from north to south magnetic pole.

# data[].attributes.body
determine earth acts like a giant bar magnet with a magnetic field that extends into space

# data[].attributes.body
Groups of atoms with aligned magnetic poles

# data[].attributes.body
its any magnets who domain remain aligned whiouth an external field

# data[].attributes.body
Are useful beacuse the magnetic properties can be controlled by the user.

# data[].attributes.body
Are repelled by an atractive to the poles this cause the electromagnet   to rotate

# data[].attributes.body
electron magnet change electrical energy into mechanical energy that vibrate the speaker to produce the sound that you hear

# data[].attributes.body
Is a device that use an electronmagnet to measure electric current

# data[].attributes.body
Includes componets called brushes and a commutator this form a closed electric circuit between the battery and coil

# data[].attributes.body
When there is a current in the coil, the forces between the coil and the permanet magnet cause the coil to rotated.

# data[].attributes.body
as the coil keep rotaiting, the currents that its produce it continued to change to direction

# data[].attributes.body
Onces the engines is running, it provides the mechanical energy that is use it  turn coil in the alternator

# data[].attributes.body
Mechanical energy is use it to rotated the magnet and the current is indused in the stationary coil

# data[].attributes.body
The electrical energy come from a power plant this most have   an energy source

# data[].attributes.body
Both use electromagnet to cunvert electrical and mechanical energy
