# data[].attributes.body
Voltage in secondary coil divided by voltage in primary voltage equals to turns on secondary coil divided by turns on primary coil

# data[].attributes.body
Generators transform mechanical energy into electrical energy

Motors transform electrical energy into mechanical energy

# data[].attributes.body
Used in cars and tribunes

# data[].attributes.body
Is a device that changes electrical energy into mechanical energy

Used in fans, cars, CD players etc.

# data[].attributes.body
Speakers: when the electrical current and magnet attract together they produce sound

Galvanometer: when the needle and wire attract to the magnet inside the galvanometer it starts to rotate

# data[].attributes.body
Permanent magnets maintain their magnetic field

Electromagnets only have a magnetic field when there is a current in the wire.

both exerts forces on magnets and magnetic materials

# data[].attributes.body
Behaves like any other magnet when there is current in the solenoid

Have two poles south and north

Exerts a magnetic force and magnetic materials

The strength of the magnetic field can be increased by adding more turns of wire to the solenoid

# data[].attributes.body
Moving charges that produce magnetic fields which depends on the direction of the current in the wire.

# data[].attributes.body
Are the two sides of the magnet the south pole and the north pole. If the two poles were south the magnets will separate. If one side was north and the other was south, then both magnets will interact.

# data[].attributes.body
If the magnetic fields are strong that means that the magnet sired in the fiels will have stronger magnetic force. The strength of the magnetic fields affects the use of the magnet

# data[].attributes.body
Is the size of magnets. One can be stronger, so it can lift bigger objects other cam be small, so it can lift smaller objects.

# data[].attributes.body
Is the strength that two magnets exert on each other the can cause them to interact or separate from each other.
