South pole
Unequal magnetic ends, attract each other
Equal poles repel each other
magnets and can be either attractive or repellent.
permanent magnet
electromagnets
Induction
Can be switched on and off
heat generation
Iron core
Magnization
align the elementary magnets in parallel
can be done by using a permanent magnet
can be done by using a electro magnets
can be done by using an air coil
Demagnization
achieved actively by applying an oppositely polarized magnetic field
reverse magnetic field
coercitivity
can be achieved by using a low-frequency generator
can be achieved by using a yoke and tunnel coils
Maurer Magnetic AG
can be achieved by a strong heating beyond the Curie temperature
can be achieved by a strong mechanical shok
magnetic
refers to a material from the moment when its magnetic induction & field strength are above zero
magnetisable
when a material has the prerequisites for being magnetized
ferromagnetic material
Iron
nickel
cobalt
magnetorheological effect is a reversible change in the flow and deformation behaviour of certain materials under the influence of an external magnetic field
