Magnetism Flashcards
electromagnetism is…
The interaction that happens between particles with electric charge (the connection between electricity and magnetism) via electromagnetic fields
A solenoid is…
coil of wire that we use as an electromagnet: a device that can convert electrical energy into mechanical energy.
An electromagnet is…
a temporary magnet made by winding wire around an iron core. When current flows in the coil the iron becomes a magnet.
Magnet
An object which is capable of producing a magnetic field and attracting unlike poles and repelling like poles.
Magnetic pole
region at each end of a magnet where the external magnetic field is strongest
Magnetic force
Magnetism — force
the movement of the charge of the electrons in the different particles
Galavanometer
an instrument for detecting and measuring small electric currents.
Electric motor
a rotating machine that transforms electrical energy into mechanical energy
Magnetic field lines
Magnetic field lines are a visual tool used to represent magnetic fields
Magnetic field
the area around a magnet, magnetic object, or an electric charge in which magnetic force is exerted.
Atoms
the smallest building blocks of matter and make up everything around us
Magnetic domains
region in which the magnetic fields of atoms are grouped together and aligned.
Ferromagnetic material
materials which exhibit a spontaneous net magnetization
Temporary magnet
a magnet made of soft iron, that is usually easy to magnetize
Permanent Magnet
a magnet that retains its magnetism after removal of the magnetizing force
