Alnico magnets are one of permanent magnets deriving their name from main constituents-
Aluminium,
Nickel and
Cobalt with Iron as base. They have distinct advantages over other varieties of
permanent magnets in terms of moderate price and widest temperature staility.
Characteristics of samarium cobalt magnets :
very hard and brittle
poor resistance to demagnetization
excellent stability over a wide range of temperature
Application of samarium cobalt magnets :
separators, sensors, holding devices, motors, relays, generators, controls,
braking devices, security systems, energy meters, speedometers etc
