Click For Summary
The BH curve represents the relationship between magnetic induction (B) and magnetizing force (H) in magnetic materials, illustrating how a material responds to an external magnetic field. Hysteresis refers to the lag between the changes in magnetization of a material and the changes in the external magnetic field, often visualized in the BH curve as a loop. This phenomenon indicates that the magnetic properties of a material depend on its magnetic history. Understanding these concepts is crucial for applications in electromagnetism and magnetic material design. Comprehensive resources can be found online for further exploration.

please tell me what BH curve is
what is hysteresis

i need matter all links are welcome

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
