magnets Flashcards
electromagnet definition
a non permanent magnet turned off and on by controlling the current through it
magnet definition
a material with a magnetic field around it in which magnetic materials will experience a force
magnetic field definition
a region in which there is a force on a magnet or magnetic material
magnetic field lines definition
imaginary lines which show the direction of the force on a magnetic material
magnetic force definition
non-contact force from a magnet on a magnetic material
magnetic poles definition
the ends of a magnetic field called the north seeking and south seeking poles
magnetise definition
to make a material or object magnetic
permanent magnet definition
an object that produces a magnetic field all of the time and cant be switched on or off
solenoid definition
a wire wound into a tight coil, part of an electromagnet
acceleration definition
how quickly speed increases or decreases
average speed definition
the overall distance divided by the overall time taken for a journey
distance-time graph definition
a graph that shows how far an object moves each second
speed definition
how much distance is covered in a given time
speed = _ divided by _
distance divided by time
distance = _ x _
speed x time
