Magnets and Electromagnetism Flashcards
any object that are capable of attracting and producing its own magnetic field.
magnet
these are the materials that are attracted to magnet
iron, steel, nickel and cobalt
it is a piece of the material magnetite that has become naturally magnetized
permanent magnet
2 Artificial Magnets
1.) Ferromagnet
2. Electromagnet
it is a metal or substance that can be a magnet in the presence of magnetic field
Ferromagnet
the magnetic field is produced by electric current
Electromagnet
physical phenomenon by the motion of electric charge
Magnetism
it is the region around a magnet in which there is a force
Magnetic Field
the ________ the two magnet is, the ________ the magnetism
closer, stronger
magnetic line of force start from _____ pole to ______ pole
north pole to south pole
the word ‘lodestone’ comes from the Anglo-Saxon word that means?
leading stone
we use these lines to indicate the magnetic field
magnetic field lines
when you bring two magnet together, what are the 2 possible field interaction that could happen?
it can be either attraction or repulsion
what happens if the opposite pole of two magnets are brought close to each other?
the direction of the magnetic field aligns, causing attraction between the two magnets
what happens if same poles of two magnets are brought close to each other?
the magnets will repel and the fields will create a neutral point where no magnetic field is felt
they are produced by positive and negative charges
electric fields
if a magnetic field points to the direction of the north pole, where does an electric field point to?
direction of a positive charge
inside a magnet, the field runs from the _____ pole to the _____ pole
south pole to the north pole
electric field lines have _______ starting and ending points
definite
he is a Danish science who accidentally discovered electromagnetism
Hans Christian Oersted
the direction of force can be demonstrated by using this rule
right-hand rule
you can increase the strength of the magnetic field by?
increasing the flow of current
coils or current-carrying wires that produce a magnetic field
solenoids
