The formula to obtain the hysteresis loss devised by Steinmetz is given by:
[ P_h = k cdot f^x cdot B_m^y ]
Where:
– ( P_h ) = Hysteresis loss per cycle (watts)
– ( k ) = Steinmetz constant (specific to the material)
– ( f ) = Frequency of the magnetic field (hertz)
– ( B_m ) = Maximum flux density (tesla)
– ( x ) and ( y ) = Empirical constants that vary depending on the material (commonly, ( x ) is around 1.5 to 2 and ( y ) is typically around 1.6 to 2.0).
This formula reflects the relationship between frequency, magnetic flux density, and hysteresis losses in magnetic materials.
The formula to obtain the hysteresis loss devised by Steinmetz is:
[ W_h = k_h cdot f^x cdot B_{max}^y ]
where:
– ( W_h ) is the hysteresis loss in watts per cubic meter of the material,
– ( k_h ) is a constant specific to the material,
– ( f ) is the frequency of the magnetic field in hertz,
– ( B_{max} ) is the maximum magnetic flux density in tesla,
– ( x ) and ( y ) are empirical constants typically found through experimentation (commonly, ( x ) is taken as 1.5 and ( y ) is around 2.0 for many materials).
Answer: c
Explanation: The hysteresis coefficient along with the frequency of magnetization and
maximum flux density is calculated first. Next the Steinmetz coefficient is calculated and on substitution it gives the hysteresis loss.
